Just want to let you know as a girlfriend it is hard to understand you don't want to be touched while sleeping.My bf does the same thing sometimes,Sometimes we can be laying next to and just snuggleing and he can't handle it.Im thinking time may be the only thing that helps.Your girlfriend loves you or she wouldn't be there.I will give you some advise (I wish someone would give him) When your awake give her a little reassurance that you love her and your attracted to and enjoy being with her.I have never been an insecure gf but the relationship I am in now has somehow lowered my self esteem a little, sometimes he is pushing away and I can't do anything about it,I just remind myself it's not him but the ptsd.I did speak to him about how I feel and it was hard as I didn't want to come off as being too needy.We as girlfriends understand or at least try.They say time heals thats what Im banking on..
