Why is he pushing me away? Daily relationship impressions?

I need guys oppinions only. My boyfriend is one of the sweetest giving people i have ever met, to everyone but me. He used to be so fucking wonderful to me and its begun to make me very depressed and irratable. I understand he is stressed about a lot but he is only acting negatively towards me.. and he has become extremely selfish about sharing space with me. He goes out and buys all kinds of stuff for himself and if I ask him to get me something a hassle same with trying to get him to spend time with me*that's like pulling teeth) he turns down bjs and its a chore to have sex or a privilege. I love cleaning and organization and cooking but if I feel like its not appreciated whats the point. Saying thank you doesn't mean anything if you have a follow comment that's negative. . I believe that everyday should be a new day to help and love eachother. When your in a relationship you should do everything to continue to improve your ways to positively impacting your partner. And 1rst impressions are not everything if you stop being that person that you met. But have no problems doing it for others. What am I supposed to do about someone who has become extremely callous and almost narcissistic.
