Yes, that blowing hot and cold is confusing. I think, most of the time, if you're emotionally unavailable, it's not a very conscious thing. Often people sincerely want to have a relationship but are stumped when it comes to leading one and being able to follow up on everything it entails. So even though he may be somewhat unavailable, it doesn't mean he's not an amazing and also lovable guy - it just means he is not in a place to offer anyone enough of himself to make a relationship work. (At least, at the moment, not with anyone who is not comfortable with what he has to offer.) Or, alternatively, he may be offering what he thinks is enough, but it's not enough for you - because that counts too. (If he is unavailable emotionally, it could very well be due to the place he is in dealing with PTSD, or it could go beyond that, who knows.)
Whatever space he is in is totally to be respected. If he is not aware of it himself, then at least you should be and make your choices accordingly.
(Another interesting though re. getting involved with essentially unavailable partners is that, quite often, if we continue the cycle, on some level, somehow we're unavailable ourselves too. If we were fully available and readt to have a great and mutual relationship, we wouldn't try to make one work that doesn't serve our needs. I balked at the first time I heard this, but I realized, for me, it was true.)
Just to clarify though, I'm not generalizing here that sufferers are all emotionally unavailable. Quite the contrary! It's just my thoughts on your particular situation at the moment. These are just theories on my part - I don't know you, him, or the relationship dynamic you're in, but if any of it resonates with you, then maybe this line of thinking is helpful.
