So I am in a relationship with a combat veteran who has PTSD and a service related injury. He goes hot and cold constantly. Last time I didn't speak to him for a week, the time before it was nearly two weeks where we don't hang out. I texted twice over two days (nice not pushy things) but when he didn't respond I backed off. I gave him some space and pulled back a bit. When he showed back up in a week I didn't want to push him so I stayed pretty low key with the text message responses so that he could come to me in his time. Then he left me flowers on my car and I still kinda played it cool but then I guess he figured I was mad at him for disappearing again and not saying anything to me for a week (which I was slightly annoyed) and so he just showed up at my house unannounced (which he doesn't usually do, but I'm totally fine with it). He told me a lot more about what is going on with him and details about his life. The problem is, when I ask why he keeps cancelling plans on me or why he is always late, he acts like he doesn't see or understand what I mean. He always does have a reason and it's always something valid but it's predictable that he doesn't show so I want an answer. Like I know when he says lets do X on Monday, that we won't be doing it so when the excuse comes for why, I already don't believe it no matter how valid. I can't help it, it just seems weird that he won't tell me why this keeps happening. Does anyone have any ideas on what's going on? Mutual friends tell me he talks about me a lot and he made sure I met his son when he came to visit so I just don't get why the only time we spend is at night and he cancels. Forgive me if I sound dumb, I get that he's a guy and the obvious possible reason it could be, but I feel like when a guy calls you his girlfriend without prompting, introduces me to his kid, does household "chores" to help me out and tells me he's really interested and wants me around in the future that I'm not just a booty call. I really like this guy but it's like he can't have a normal go on dates/hikes type of relationship. Is he afraid if I spend an actual day together I will see his difficulties or something and leave? I just don't get it.
