Why is my boyfriend avoiding sex and taking me to his house?

We never had this issue before until now. I ask him what time I’m seeing him and he changes the subject completely and he hasn’t been taking me to his house or having sex with me. I’ve been to his house before and he lives with my mom and I met her before. Now lately he hasn’t been in the “mood” for sex and avoiding taking me to his house. What’s going on with him?

I meant he still lives with his mom. Not my mom. And when I bring up sex he gets mad at me and thinks I “just wants sex”. Why is he being weird?

Why do you think he’s acting like that?
