I've been confused lately

I love my fiancee with all my heart but I just don't feel he is into me anymore.  He has been working a lot and I understand that he has to work a lot of overtime to get caught up on bills that need to be paid.  But the issues are he doesn't talk to me anymore like he use to. Communication has been lacking like crazy everytime we try to talk he either tells me its not important or its taken care or he falls asleep.  Everytime we are together now he just sleeps all the time.  The rare moments where he is in the mood he falls asleep there to.  
Lately I have been having nightmares about the sexual abuse and rape that I have been experience and for some reason when I get into these nightmares nothing wakes me up at all.  He usually holds me until I wake up but the night before last he left to the living room and just left me there to wake up scared.  Last night he basically almost pushed me off the bed and told me to hurry up and snap out of it because he has to be at work in a couple hours.  Both hurt my feelings but I am not sure what I can do its not like I can help what happens.
Maybe I am just over reacting I don't know I am sure when things slow down things will be better I guess or I hope.  The part that bugs me is he is getting annoyed at my nightmares like I have control over them.  Hopefully things change in the future besides that stuff everything is going good i guess.  My pain still is high my mirgranes are just as bad but that is just everyday normal stuff.
