I'm 25F (straight) &amp; my "best friend" in college is a 24M (gay). So in college, I became really good friends with this kid I'm going to name Lance. Lance was very closeted, and he came out to me; I was the first one he came out to you. We became extremely close, and I helped him eventually come out. I really looked up to him because he had his shit together in college, and I was personally a mess. I struggled a great deal with my drinking, and I couldn't get it under control. My behavior wasn't necessarily stellar, but Lance still stuck by me.

After we graduated, Lance moved to DC and had a mental breakdown. I went to visit him and then I realized how bad things were. I eventually got a hold of his mom, who flew out to DC. We ended up staying with Lance for a good two months. I was able to do work remotely at the time, and Lance eventually went to a behavioral mental health center/rehab for 45 days. After he got out, he was doing fantastic. I personally saw a huge difference in him, and he had light in his eyes. 

I decided that I needed to get sober and went to rehab shortly after. I've remained sober since, and I am so happy. Lance did not go to rehab because he was a drug addict or alcoholic. He is severely bipolar and needs to be medicated. I genuinely believe that his mental breakdown was the first indication of bipolar 2. Before going to rehab, I went to DC to visit Lance. His mother has always been a little bit wacky, aren't we all, but this trip really opened my eyes. She slut-shamed me, and it became apparent that she had a lot of issues. Both Lance and her are very paranoid people. However, my mom is not in the picture, so I put up with it. His mom and I had also become close during the summer of hell.

Fast forward a year later. I'm still sober, and I'm thriving. I made a bunch of new friends in the area where I live when I got sober, and I was so thrilled. One of these new friends I introduced to Lance. This friend already had enough problems himself, but Lance was highly toxic. Months later, after I introduced them, I was aware that Lance aired all my family's dirty laundry, including things that I could fight in him.
Meanwhile, in college, I did everything I could to protect the secret he was closeted about. I felt so hurt and betrayed. I then started getting messed-up texts from his mother and boyfriend telling me to drink, bring up my trauma, etc. I did not deserve this, and it was unprovoked; I clarified what was going on to Lance. Lance did not stick up for me. If anything, I think he was stirring the pot.

So Lance has had another mental breakdown recently. One that has resulted in him getting fired from his job, justifiably so. He's been claiming that his new boyfriend is beating him, specifically his mother, but won't convey this information to others. Personally, I don't think that his current boyfriend is destroying him. I believe that accusations like that ruin lives, and it is beyond offensive to Cry Wolfe like that. But on the off chance that he isn't, maybe he's just severely brainwashed. His mother has also lied so much that I don't even know what to believe with her. He also has even more family dirty laundry that I could quickly and easily air out.

My last straw was whenever he told me he was coming up to Los Angeles. I get a minimal amount of time to see my brothers and I made it extremely clear that if I came out to Los Angeles so he could stay with me, I would be happy to do so. Still, he cannot bail because I'd be leaving my brothers. I'm not kidding. This idiot bailed. Whenever I blew up at him, he literally texted me back, "You're fine." Also, all of the flights were full-back to my hometown, so I couldn't even fly home. My dad has an invoice ready to send to his dad of all of the cancellation fees, flights, and any expenses that I incurred due to flying out here. I think that my dad should send it honestly. He gave me his word that he was coming and was not going to bail for different times.

So here's my dilemma. Lance did not leave me whenever my drinking was at its worst and was a substantial contributing factor to my getting sober. He has been nothing but encouraging about my sobriety, and I can't even imagine the look on his face if I were to tell him that I started drinking again. It's actually stopped me from drinking before. Even though I know that sobriety is a personal choice. We went through a lot together. But I think the damage has been done, and I need to walk away. I'm not necessarily sure if he's serious about getting help or treatment. He told me he wanted me to sponsor him and then lied about drinking on Thanksgiving. 

Would you walk away?
