I need help.

hubby is active when I'm not fertile but once I'm in my fertility window he is no longer active .I confronted him and told him how unhappy I'm during my fertile week we made love only twice I wanted it just once again since I have reached my Peak he couldn't. I'm really frustrated I feel like going out to look for a man to get me pregnant I need a child badly I'm 33 I don't have much time anymore. I'm ovulating now and hubby said he is worried work pressure I try to put him in the mood his manhood didn't stand this always happens during my ferilitt window. please ladies I need your help, is there something I'm not doing right
