Dear all, 
I need advice and I have no one to ask, because It’s super personal and complex. 
I fall in love with man who has PTSD (we are both around 30th) and I don’t know how to act in my situation. We are dating for few months and I feel something like that for the first time. Before we started dating we where friends and he was super hesitating about us dating, but he never explained why. I asked for several times, but didn’t get the explanation. But we where cuddling and kissing a lot. After I while I told him, that I want to go on date with him. And after some reassurance and persistence that everything will be fine and that I really badly want that he agreed and ask me out. 
Between us I can fell electric power and he told me that he is feeling butterflies when we hold hands and kiss me. We chat a lot and call each other daily. We also spend few days together and it was super intimate experience - sharing deepest secrets, talking about our fears. The way he touches me is unbelievable. He is super tender, fixing my hair, holding my hand all the time, kissing tip of my nose. We care for each other super much, and I’m sure that we would do for each things that majority of new couples wouldn’t. 

The problem is that he had sever abuse when he was child and teenager. He still struggles a lot (bad dreams, feeling that he can’t do anything, powerlessness, fear). He also lost his job due situation in our state. He doesn’t consider himself beautiful or smart. I’m his second girlfriend (first one was abusing him). He is super talented, beautiful and kind. 
On the other hand I come from wealthy family and I have super good job. But I never told anything disrespectful about him. I think that he is the man that I want to spend life with. I will be there for him.

The main question is why he doesn’t want to tell me that he wants to be my boyfriend. He told me several times that ‘we will see about us’. That he is afraid that he will hurt me. That he would still be there if we don’t continue dating. That he doesn’t know what he wants. That he is lost. I feel that he is breadcrumbling me from time to time about commitment, future, that he wants to be with me. I don’t want pushing him into anything. So I didn’t told him anything about it. From time to time - when I’m alone I think about him leaving me, because he can’t be with me. I feel terrible, because I tried super hard and I have strong feelings. 

I just want to know if I’m delusional to think that we will stay together. And what’s the main reason that he doesn’t believe in us? I know that it’s hard to believe in something if you don’t believe in yourself. But it’s hurting me and I’m afraid that I will fight for us and on one point he will give up. 

Thanks!
