Hey Girl,
I just saw your post and wanted to encourage you to choose life for your baby (if you are indeed pregnant again). You said that if the choice were yours you'd choose to parent this child too. Well guess what.. the choice IS yours.
I've been in your situation of not wanting to ruffle the feathers of my boyfriend. When I found out I was pregnant the first time I was so afraid I would loose him:unsure: . When I finally chose to carry my baby rather than killing her thru abortion, I told my boyfriend that I would give her up, thinking that he would take it better and stay with me. But ultimately, I couldn't do that either...(although I think giving a child up for adoption has got to be the bravest and very responsible thing to do). But I had to first come to terms with the fact that he may walk. He did for a while, but eventually came back around.
Anyway, either direction you choose, please choose to give life to this baby. If you abort, then you will have a lifetime of wondering, regret and hurt, knowing that you killed your daughter's brother or sister.
You are not going to be 18 forever and your children won't be babies forever. You all will grow up and times aren't as hard as in the beginning. I'm not saying it would be easy, but it would get easier as you get older.

((Hugs)) to you.
