I'm pregnant and my husband (soon to be ex) wants me to abort
Today I found out I'm 5 weeks pregnant.
My husband had an affair about a year ago and he said that a few months before that he realized he didn't love me and he wanted to leave. We've stayed together over the last year because neither one of us want to be separated from our child and I would have a really hart time supporting my 2 children from a previous marriage without him. I love him very much and I have always wanted to work on our relationship but he hasn't been willing. I've done what I can do deal with his lack of love for me and we've still been physically together even though we're not there emotionally. We've been very careful, but I've not been on birth control because I have issues with birth control, (My oldest two children were conceived on the pill) I'm allergic to Depo Provera, and we tried an IUD after my last pregnancy but it ended up nearly falling out and had to be removed. We talked about getting my tubes tied, but I'd always wanted to have another child and at the time we were still together. He also talked about getting a vasectomy but couldn't go through with it.
We were not expecting this and I've not even told him yet, but I'm afraid to because I know he doesn't want another child. I'm very pro-choice, but I love my husband very much and I love my children very much and I just don't think I'll ever be able to live with myself if I go through with an abortion just for him. Our relationship is not going to make it regardless of my decision so should I just do it because it's what he wants? My family is going to be opposed to me keeping the child as well so I'm going to be alone in this, it's scary, but when I think about how much I love all my children I feel terrible thinking that I'm actually considering ending the life of one before I ever meet him/her?
What do I do?
