Hi all, I’m an 18F and I need support really badly. 

My ex and I met in December of last year and I was swept off of my feet. We moved in together 3 months later &amp; it was honestly my healthiest relationship to date. We broke up about a month and a week ago now. 

The catch to all of this is when I moved in, my bestfriend of 7 years also moved in. I got kicked out because I wasn’t on the lease but my bestfriend still lives with him (&amp; two other roommates). 

Since the split, I have not been able to stop thinking about how they probably are gonna hookup or he is going to try and get with her. About 4 days ago I finally brought it up to her that I was feeling like he was going to make a move on her and she was very reassuring and said she promises nothing like that would EVER happen. I believed it for a day. Now I’m back at square one, just constantly thinking that they’re hooking up everytime their home together. Why can’t I just believe her? 

How do you guys cope with intrusive thoughts. I feel so horrible.
