What’s wrong with me!

So my husband and I have been married half a year and together almost three years. We used to have sex EVERYDAY when we first started dating. Now, I don’t feel the want to have sex at all. I could go months without it and I would t care. It’s not that I don’t not want to, if he wants to, I’m down. But I’m never like “I want to have sex”. When we first got together, I was dating another guy and I was going behind his back because he was super abusive and would t let me break up with him and I was just scared to come open and tell him I found someone else( I eventually ended up moving out of the apartment when he went to work one day and haven’t talked to him sense). So I dont know if it was the adrenaline of going behind this abusive psycho boyfriends back that made sex enjoyable for me before or what. Now when we have sex, it hurts me. No matter how much foreplay we do or how much lube we use, it hurts afterwards. I need help, my husbands getting super frustrated and thinks that I’m not attracted to him anymore. I dont know whats wrong with me but I don’t think it’s normal that my sex drive us this low. What should I do?
