Shortish long story, 
I (24M) have been talking to a friend of mine (21M) who has BPD and recently went through a breakup. We were really cool for a while but everything has slowly begun to get more and more complex as days go on. Mind you I’m a goofball and just over loving in general but as of recent I’ve been dealing with some mental issues, depression, which I’ve been on medication for totaling ten or so days. Through this whole process my friend has been very supportive and just overall a sweetheart, but we were hanging out in the common area together while he was just playing some video games just talking and joking around like normal, then it started getting late so we were both about to leave, we hugged for a second and sat back down, we talked a little more and he asked if I wanted to cuddle, which is pretty fine with me, I don’t really like people that way and I’m also demi so it’s complex to say the least, however I accepted because honestly why would you say no to a good cuddle session? A few days go by and we just do the same thing every afternoon, talking, cuddling, hanging out, joking around, etc. but as he gets done playing with his friends and we start joking around like normal, but he kinda makes this joke that’s a little more than a joke, he wanted to push the limits of my comfort zone. (If you know anything about me, it’s that I have zero boundaries as long as the other person is comfortable with whatever they want to do) so we start making out, and we were laughing about it being total idiots, but for some reason it felt like he was really getting into it, kinda putting some emotion out there, so that thing about being demi, yeah, It was like a light switch flipping on and immediately I caught feels. Well after all that we just sat and joked for a while then went back to our rooms. Everything was cool, but now I have feels, and I think he does too, but I know he is still getting over someone so I was trying to be cautious and make sure he is okay with everything. I don’t want to do unnecessary damage you know? Moving to yesterday, we were hanging out, except I could tell something was off, but I don’t like to trigger anybody so I leave it be unless he feels comfortable telling me, well we both have a few drinks, I know it’s an awful idea, but we just played cards and joked around, watched his roommate play overwatch, just kinda had good innocent fun. After a while you get to that point of being drunk where you have zero filter and just start spilling your whole life story, but it wasn’t like that at all. He stood there and we hugged for a second and we both got close like we were going to kiss, we’re both drunk at this point and he points out he doesn’t want to do anything romantic and such unless he’s sober, I 100% respect that. I tell him something along the lines of, “I support that, thank you for telling me before I made you uncomfortable” and he still looked pained by something, so I asked. I’ve never seen such heartbreak fall over one person in such a short time. To summarize what he said, we both like each other, but he wants to be able to love me for me and not for a replacement, but also he still feels incredibly attached to his ex, but still wants to keep me close as a friend, but he cried for hours trying to not catch feels due to breakup. I don’t know what I need to do other than maybe ask if he needs space, but I don’t want to affect him any more than I have, however I caught feels, as well as he did, and also don’t know what to do? 


TL;DR I caught feels, other person going through breakup sadness, both admitted feels, big confuse
