Navy girlfriend in need of some support

Okay, Me and my boyfirned have been together for about 6 months now. Our problem or at least my problem is he doesnt show affection at all. We first met in a dateing site and sense then I moved in with him. When we first met he was adoriable and always wanted to touch me. Sadly that lasted only over that first weekend. We dont hold hands I dont get kissed more then twice a day if we cuddle in bed I have to ask him for it and then it seems as if he doesnt want to. and when hes away he will say how much he misses me and what all he wants to do with me when he gets home and when he gets here nothing changes. Half the time I even have to wonder if he notices me there. Ive brought this up to him before he said he would work on it, it never happend.. I brought it up again after my mother and brother as well as friends noticed he doesnt do anything of the sort in anyway sweet. he said thats how he was raised and doesnt think its going to change. Im to the point where I cry over it and upset. Im not sure what to do, I know leaveing him is not an option because this is where I want to be...with him. I just would really like to understand this more on how I should go about it.

Do you drive his emotions? Do you impact his life in any way? Do you make him feel like a man like no other person can? That's terrible of how little affection he has shown since the first weekend of moving in. I think perhaps he's afraid to be in a committed relationship or he has had some past trauma of some sort, or maybe nobody in his life has ever shown him affection so he doesn't know how to show it. Don't forget that relationships require 50/50 effort from both sides. The man does not need to show the affection all of the time, try to do it as well. Don't make him do all of the work, put in your share too, see how much it affects the relationship. Communicate. Talk to him about how you feel, what you think, be thorough with what you say and find some answers from him if possible. That's all you really need to do. Don't hold back, if you've got something to say or ask, then talk to him! If he doesn't think he'll change, perhaps try to give him a reason to do so. You love him enough to tolerate this, but for how much longer? Sometimes what you want may not be the best. As long as you AND your partner WORK TOGETHER toward a solution, then it will succeed. Because honestly, if he doesn't want to try, then I don't see why you have to anymore.
