Has ptsd been an issue in your relationship?

I started seeing this guy, started to sleep with him he's been separated for a while now but we were just friends when he was still together with her but until the separation is when we started to have sex. Well anyway, he's an army vet and sometimes he gets into these moods and I've been one where he's taken out the anger on me especially when we both thought I was expecting but it turned out I wasn't.Well it's been hard for myself and him because he doesn't want me to see him like that and it hurts because I feel like he doesn't want to see me. We haven't had sex in almost a month neither have we eeen each other but I mean it's understandable because I have been dealing with bronchitis for 20 days now and he got sick from getting up early to work. But like I feel like telling him to forget about making plans with me because he hasn't been keeping his word. We both arrange to make plans one day and then he doesn't text me anything. I feel like giving up but that just isn't me when it comes to a relationship because my last one didn't end so good. It's been different with army guy like I seriously don't know what to do with him. I also wanted to point out I also have PTSD from a traumatic experience a while ago, so I try to understand but sometimes I feel like he's also pushing me away. I've told him that I feel like he's pushing me away but he is insists that he isn't...so I don't know.....We have our sweet moments more than we do these moments but maybe I should just talk to him about it ? I haven't spoken to him since Saturday morning at 3am. He hasn't sent me anything either...any ladies who can relate to what I'm going through and what did you do ? 

Advice would be appreciated
