I cheated on on my husband and now he wants to have sex with other women because he's jealous ?

I had a 1 time encounter with a man searching for affection I dont receive from my husband. I felt disgusting and horrible after and realized what a mistake I had made. Soon after I became pregnant with my husband and my 3rd child. The affair came out shortly after I found out I was pregnant and we've been struggling with our relationship as to be expected. I love my husband and have been trying to repair us the best I can. He informed me he doesnt want to go and hurt me out of revenge, but hes jealous I got have sex with someone else and he's been wanting to have a new sexual encounter just for fun. He tries reassuring me he loves me and wants to be with me until death but I cant even look at him without getting sick to my stomach. I was feeling empty and wanted to fill the void I had been feeling when I cheated. ( I am also a victim of child molestation and physical abuse). We have been together for 8 years now and Ive never felt so much remorse in my life. Should I be so angry that hes just wanting a sexual newbie for the fun of it? He says im being a b**** because he's at least telling me about it and its not meant to get back at me. What do I do? Im 5 months pregnant now and I dont know if hes right. We both say we want to be together forever but how do we repair the damage done and how to I handle this new issue he has thrown at me?
