commitment or everything was just plain heartache?

someone said that I have gotten what I deserve from my live-in relationship. They think that I have made a lifetime commitment and should stand by it. I’m sure that person assumes that all the fault lies with me. Maybe it does. The problem is that I am miserable in my relationship. My boyfriend is a good person but not a good boyfriend. When I try to talk about the problems in our relationship he usually won’t even respond or he will say that he needs to change. But, he doesn’t follow through with any effort. He worked hard and he loves it more than me. He said that with his own mouth. There was a time when I didn’t love anything more than him. I don’t even know IF I love him anymore. My feelings are all confused. The only reason I haven’t left him is because I did make that lifetime commitment to him. I thought he was making the same for me. I gave up my whole world to move in with him and be his girlfriend. He didn’t change his life at all. What he wants to do or thinks he needs to do always comes first. I understand that his work needs to be a priority but I don’t understand why it has to consume him. I haven’t worked outside of the home because he didn’t want me to. I’ve come to the point where I just feel like his personal assistant and mistress. My whole world is about doing things for him. Keeping him happy is what I have been devoted to. He never goes out of his way to make me feel special. We have been together for 5 years and he never even buys me a Christmas present. He says he doesn’t have time and that he wouldn’t know what I would want anyway. Maybe if he paid attention to me, he might. I try to act like it doesn’t hurt, but it does. Something as simple as a little love note would do wonders. work and his side of the family are what is important to him. I basically just see him for breakfast and lunch. When we are together all he can talk about is work. I can’t help it if I have other interests. He just flat out doesn’t. There are always two sides to every story. Perhaps I do deserve to be lonely. I just feel like I have sacrificed myself for him. I’ve lost part of myself in the process. I don’t know if I can face a lifetime of this. I pray about it everyday. I think I chose the wrong man to commit my life to. Should I stick with this lifetime commitment where I feel miserable?
