Hi, everyone. So, a couple of months ago I ended a relationship with someone who had previously been diagnosed with Obsessive Compulsive Disorder. When we began dating, he seemed like the perfect partner, and he told me up front about his diagnosis and that he hadn't sought any help for it. Being so into him, I didn't really consider that information to be concerning. A couple of days after we became official, he asked me how many partners I had been with before him, and I told him that I'd been with 8 other sexual partners before him. He then proceeded to panic, saying that he wasn't sure if he was comfortable being "compared" to 8 other men. It was like I had flipped a switch. He went from being calm one second to completely losing it the next. It was as if he was furious with me, like I had been cheating on him with these 8 other guys, even though all of that was in my past. We then went the rest of the day without speaking and I was in complete shock. The next day he apologized and said that he knew he was being irrational but he couldn't help but think of me with all of those other guys and feel inadequate. This was a reoccurring event in our relationship, him lashing out and then apologizing, saying that he just had "no control" of his thoughts. He would also constantly be aligning items around the house. For example, if a book was sitting on a table, and the sides of the book weren't parallel to the sides of the table top, he HAD to straighten it. Another example: if the back of the couch wasn't perfectly parallel to the living room wall, he HAD to straighten it. As far as the OCD symptoms that most people are familiar with, that was probably the only symptom he displayed regarding cleanliness, tidiness etc. But it just seemed like every few days he would become aggressive and lash out at me over my previous partners, calling me a slut, whore, etc., saying that he just knew I was comparing him to all of them and that he was just "another d--k" for me to "ride." He would make me cry and feel like trash on a regular basis for absolutely no reason. Then, the next day he would always apologize and say that he just couldn't control his thoughts. Eventually, he lashed out at me and then the next day when he apologized I told him that I couldn't do it anymore. That night, he blew my phone up, leaving me voicemail after voicemail apologizing, begging me to take him back. After 8 other phone calls, I finally answered, and he was crying and begging me to forgive him, and I said that I thought he needed professional help and that I, as someone who struggles with severe anxiety, just couldn't handle his outbursts anymore. He then told me that if that was the way I felt, then I needed to block his number, or he would call me every day and leave voicemails just to tell me how much he loved me. At the time I was unable to make the connection between that and OCD, so I didn't take him seriously when he said it. I just thought he was saying that trying to win me over and convince me to give him another chance. So I didn't block his number. And the next night, he started texting me saying things like, "So you're serious about this?" and I never replied. And then a couple of hours later he started trying to call me. He called six times and left a voicemail each time begging me to let him talk to me before I answered. And when I answered the phone, he started lashing out at me again, saying things like, "I knew you never loved me," "I was just another dude for you to f--k," "How many other guys have you done this to? I don't believe you've only been with 8," and he kept calling me a slut, over and over again. So finally I just hung up on him, and he immediately started sending me nasty text messages about what a "heartless whore" I am. So I finally blocked his number. Then I blocked him on all social media that I thought there was a chance of him using to message me. Last week, I checked my twitter, for the first time in forever, and as I was scrolling through my notifications, I saw that he had followed me three days prior. I went to his profile to find that he had since unfollowed me. I proceeded to block him on twitter. He and my best friend follow each other on twitter, and the very next day he tweeted something like, "I just want her back. I know she's on here. I hope that somehow she sees this," and my friend sent me a screenshot. Then, the next day he tweeted something about how he had wasted his time on a "slut," and my friend showed it to me. Then, the next day, he tweeted something about wanting me again, the next, another tweet about me being a slut. Then, a few days later, I was on twitter again, reading some of the stuff on my favorite musician's profile, and I just happened to accidentally tap one of them with my thumb, and it took me to the tweet's details, right? Well, my ex had made ANOTHER twitter account and had been trolling my favorite musician, I guess in the hopes that I would see it?! By this point, it had been, like, two and half months since we'd even spoken! So, to be honest, I am a little bit concerned that he may be obsessed with me, and I'm not saying that to sound vain. I am genuinely concerned. So earlier today, I was thinking about all of this and decided to go online and see if any of his behaviors could be linked to his OCD. Well, I learned that aggressive/angry outbursts are actually very common occurrences for people who suffer from OCD and that many people who struggle with OCD often say that they have "no control" over their thoughts. I also read that it is common for adults who have OCD to develop substance abuse problems, and he is an alcoholic. I also read that OCD can be linked to depression, and there were often days that he would just shut down and not want to see me or talk to me and after these episodes passed, he would apologize and tell me that he was just "sad for no reason." I really feel awful for abandoning him because he obviously needs help and guidance very badly, but at the same time, I know that being with him was detrimental to my own mental health. His outbursts would often cause me to have anxiety attacks. I don't think I have any interest in rekindling our romantic relationship, and I really hope that he's eventually able to get over me and move on, but I'm also afraid that if he does move on, he'll put other women through this emotional abuse. I really want him to seek help but I have no idea how to convince him and I also don't know if it would be a good idea for me to confront him about it. I had mentioned before when we were together and he got angry and started cursing at me saying that I didn't know what I was talking about. And now, I'm not sure if he's obsessed with me, or stalking me, or what (???), and if I were to confront him, I'm not sure how he would react. Does anyone have any suggestions regarding who I should contact about this or how I can convince him to seek help without potentially putting both of us in danger?
