Wow are you kidding me?

Fiance has decided to do pull out while I am pregnant. This is a suprise pregancy. I chose to keep the baby. He says he chooses to pull out just in case i miscarry that way i dont get pregnant again. I know he is pulling out because i made a choice and he wanted to make a choice that would hurt me. I didnt make my choice to hurt him. What do I do? This is a difficult thing to deal with. Im hormonal and soon I will probably get really horny. HELP!

UPDATE: you ladies already helped!!! I just told him how it is. And that i had no intentions of being selfish, that he had a choice in the matter and he didnt put it out there. And that if he isnt on board before 2nd trimester that i will start making plans for myself and the baby.
