My boyfriend and I, since Tuesday have had really bad days, yesterday, he completely ignored me, only to come back today and when I told him I had done something stupid and personal I said I wouldn't, he said he didn't earn the right to overreact and went on to explain why. He said he recently had started talking to his ex again, which is completely fine by me, I see no problem with that. But he said after a day or two of talking, she started to think it was OK to attempt to get him back and they developed feelings for each other again for the one day I was ignored. He said however that he immediately blocked her after she tried to take things further, feeling guilty about knowing I trusted him to not develop feelings for others like that. I'm such a nice person and love him so much, all I could do is breakdown. Since I suffer bad anxiety, thoughts flooded my mind about him never meaning anything nice he's said to me etc and it took me an hour to answer. When I finally did, I was acting all bubbly and normal to try and throw him off of how I really felt. Part of me is disappointed, part of me hates him and never wants to talk to him, another part of me still loves him and knows I won't manage a day without talking to him so I just forgave him. I feel so broken. I can't tell him how I feel, I find it impossible and I don't know what to do. Am I overreacting? What would you do?
