You seem to be at a very hard point in your life and I don't think there's anything I could say or anyone else could say that will make this any easier for you. It seems that your fiance wants to spend time with you before you two settle down to start a family so having a child at this point seems like it would be a greater burden on your relationship than if you don't. I don't mean to be indelicate by asking this but you know that you can always conceive again later if you do go through with the abortion, right? Whatever you decide to do, please let us know and we'll support you one way or the other. Good luck to you.
