Sex drive/ pms?

Rio

So, my best friend and I are sexually active, together. like all the time. But lately, In the past month I haven’t been up to it. He usually doesn’t come up with the idea of doing things together unless we’re at one of our houses but I just had a mental breakdown over the fact that I didn’t want to get him off today. I don’t understand it. I’m still upset over it. The thing is, we used to date for two years but now we’re bffs, and also I’m still in love with him, he has no feelings for me other than friendship and sexual stuff. Soooo yeah😭🙄 does this mean I’m getting over him or what?
