Having a hard time

We have been ttc off and on for the last 8 yrs. I have been on clomid and metformin since I have pcos. Lately when I am in my ovulation window it seems my husband does not want to step to the plate. He is always saying he can't wait for us to have child but we usually dont have intercourse anyway. This is so very frustrating to me and I have tried to approach him gently but it is really stressing me out. I truly feel that this will never happen. Just venting ladies sorry.
