Am I being unreasonable?

I'm currently on the patch, which has failed me in the past, and I'm trying to get the Mirena but considering it's not covered by my medical I'm having a hard time. I'm calling Planned Parenthood tomorrow. I told my fiancee that if I get pregnant I'm aborting it. I don't want to be pregnant again. I hated it. He is against abortion but doesn't want to get a vasectomy either. He refuses to use a condom but told me that if I don't have sex with him he's leaving me. I told him if he doesn't want to get a vasectomy then he has no option on my choice to abort if I become pregnant. His family says he shouldn't get a vasectomy because he wants more kids, but we're getting married next May so that's unlikely. They say abortion is murder, no murder is the unlawful act of killing someone abortion is legal. They say it's killing an innocent baby, no it's removing an unwanted body of cells from MY body. They say it's wrong, if having an abortion is wrong so isn't having a parasite removed because a fetus and a parasite are in essence the same thing. They said we can give it up, that doesn't change the fact that I'd still have to be pregnant and that's what I'm against. Plus there is no guarantee the child would find a home. While statistics are in it's favor it still might spend it's life in the system and that's no better then abortion. They say give it one of them, my fiancee said he can't see the child and not be it's father. So you see what I mean. He's against abortion but doesn't wanna get a vasectomy, use a condom or stop having sex till I can afford the Mirena. So am I being unreasonable in asking him to understand and at least meet me half way by doing something to prevent an unwanted pregnancy?
