Basically no sex in a relationship?

My boyfriend just told me that he's too tired after work and exhausted on the weekends to have sex. Basically we aren't having sex anymore. Sex is an important part to me because I have a mid to high drive and idk how to feel about it now

Edit yes I've tried to talk about it. He brushes it off and says he doesn't wanna fight and that's the end of the conversation. He knows I want to and he just doesn't want to

Edit, some of you are talking like nuns. Oh it's okay if we don't have sex hehe. A normal relationship has sex frequently.....
