What do I do?

I’ve been with my boyfriend for 3 years now and recently our sex life has gone to shit, no there isn’t any cheating going on, life has just been so stressful that we aren’t even enjoying life or each other right now. He is very money driven and I feel like all of our conversations are about nothing but money which bugs me because I am not money driven at all. I’m more about enjoying the little things. I need a way to help reduce the stress that we are both experiencing with being frustrated about stuff and money so we can start enjoying each other again. I’m at a loss right now because I can’t think of anything. Please help!
