My ex and I had a messy breakup. It started with me panicking because I guess I have relationship anxiety and I’m more open with my feelings. My ex really isn’t and when I opened up, he got overwhelmed and broke up with me. The process of us being friends again was a long time, with us sort of digging at each other and I will admit i was sort of an a**hole during it.

Eventually we talked again and now we are friends again he finally told me he has intimacy problems that are new and unexplored. He apparently fell out of love with me for a long while, thinking it was splitting. 

I miss him and our relationship a lot and I’m wondering if there was still something I could have done, or if I did something so badly. He told me he has issues opening up as well.

I wanted to know if this is an actual thing, I wanna learn more. Thank you so much.

TL;DR: my ex broke up with me because he lost all intimacy, he says it might be borderline related. Can people with personality disorders fall out of love so sudden?
