Confused....

So my SO asked me back in Jan of last year when I was going to have my Mirena removed. I asked why and he says cause he wants another baby. We have a 12 yr and 11 yr old. So I got it removed and w we began trying I'm 44 so I started taking supplements to improve egg quality well fast forward about 6 months and he now accuses me of only wanting to have sex around ovulation time and wanting it when he's tired or after it's time for him to go to bed. He smokes because of anxiety but throws in my face well I can't have a baby by myself, or that he's doing all the work i.e planning, making advances etc. But he's so high that he can't because he is in a out there state. We were having sex one time and he says that he can't feel anything( mind you cause he's high) but it hurt my feelings at the time, or we are in the middle and he can't finish. I done this at his request because I want another baby too but I'm so tired of crying and taking all these pills I just want to quit altogether.
