I got broken up with yesterday

We’d (he’s 24 and I’m 26) been together for almost 6 months. I know it’s not a long time, but I formed a bond with him that I thought would last. For the past maybe week, week and a half we’d been having problems. He accidentally rear ended a car, and that just unraveled everything. He became really distant and shut off towards me, little jokes I would make would cause him to ice me out, and he would get defensive whenever I’d tell him that something he did bothered me (he’s done this all throughout our relationship). I’m the “let’s talk things out” kind of person whereas he’s not. When I would ask him about his feelings about certain things pertaining to himself and our relationship, he would take it as me “picking his brain.” I thought that maybe I was setting a good example for him, but these past few days have been really difficult. He just hasn’t been connected emotionally, and it put a strain on me. He kept saying he felt as though he was torturing me. Earlier on in the relationship, he told me that he feels as though he’s a fraud when he was with me because of my talents and how I looked (I’m not claiming to be outstandingly gorgeous). I just felt terrible that he felt that way. He would often refer to himself as a chud. I would tell him to stop saying that. I’m just sad that he broke up with me. I’m sad that the end of the line for him was me telling him that if he wanted us to work, he’d find a way to make us work. I genuinely did try my best to be accommodating of him and his feelings. All I can say is that I tried.
