Search Results: what to talk about with your boyfriend feelings

Have you ever got into a situation that you think your boyfriend is the problem, but in reality, you're the problem?
That's me right now. Let's called my boyfriend A, and the girl he has feeling for B.
I've been with A for a year (we started dating in January) and in September, I started to notice he talked to this specific girl and I warned him that she had feeling for him but he didn't listen to me. I was uncomfortable about it so i started to give him attitude and we started to fight over petty stuff.
When we finally talked about our problem, he told me that he talked to his friend (B) more than talking to me because I gave him attitude, and he started to treat B as if she was his girlfriend (hanging out with her, going to concert, bring her to dance practice,...). When I confronted him about his feeling for B, he told me that he only liked her as a friend but when he posted her photo on his Instagram stories (twice), he always hid me and told me that he knew i would be jealous even though i told him i was cool about it. Plus, he didn't celebrate my birthday (or get me a gift) with me but he celebrated her birthday instead. He put a bunch of heart emoji in her contact, and they never stopped talking (Every single day). B has two Instagram account, one that she posted her personal but the other account, she posted a bunch of photos of her and A. She puts caption like "He's cute", "me and a routine: wake up, play game for 5 hours.", "get a man like him". It was really hurt for me to see those photos but why would he tell me that he didn't have feeling for her but she would post photos as if they're dating? Furthermore, he blamed that this relationship is doomed because of me, and he didn't change or anything. My friends said that i'm really feeble-minded to stay with him but I felt like it's all my fault in this relationship.
P/s: I'm 17 by the way, i accidentally put the wrong age on my profile.

LONG STORY SHORT: I’m in an abusive relationship his ex beats up any girl he tries to talk to we met at work. We started off as hook up. Me to get away from my abuser ( feel stuck) him I guess he felt lonely. He didn’t care at first and then we would start arguing like couples do and he’d be mean id be mean however we never stopped talking. We work together by the way. So he’d get drunk tell me he wanted me to be his id say I wanted him to be mine but when brought up sober he’d deny deny deny. So I’d deny but I secretly had feelings for him. So we went out downtown and he called me baby in front of a group of guys because they were looking at me. I finally the next day asked about why he called me that and he denied denied and then I asked him again during text and told him to chill out about being so defensive because I liked it which he replied with “ mhmmmhm” which he not replies like that when he has nothing to say but wants to say something. After this incident he starts to look scared of me acting nervous not looking me in the eye and kinda avoiding me but still trying to get my attention at the same time. So then I asked if he cared about my situation and he said “ why did u want me to care, cause I don’t” but I could tell he did. Next day he kept bringing up my abusive boyfriend and kept asking why haven’t I left yet. And what I’m waiting for. I then tell him I’d rather be with him which he turned around looked very shyly and said “ well your still with him so...” and tried to his whatever he was feeling ( he can’t express his emotions well we’ve talked about it) now he’s acting EXTREMELY ODD now and awkward and shy. Why is this?
