What am I doing wrong? 😫

So me and my boyfriend have some pretty good sex, however it’s literally never. I can never get him in the mood or when I do he only wants to do things that I’m not really up for and I can’t tell if it’s cause he knows I don’t want to do it and he can get me to stop asking by urging those things only or what. He’s been pretty distant and not really wanting to do anything with me watch movies, hang out, etc. I’ve been trying new things to get him going I’ve been trying old things that I KNOW used to get him riled up and nothing is working. What’re your guys thoughts on how to get him to want me again like he used to?
