My husband left me for another woman and I just found out I am pregnant?

Well, it sounds like you need to give this guy the boot. Unfortunately with the pregnancy this is complicated. He does have a right to the child. I guess you guys will just have to figure out custody. Do you really want a guy like this around? One that makes your daughter so confused and hurt and seems to feel it was a burden to raise her? These are hard questions to ask, but you need to ask them. You do have to tell him eventually about the baby, especially in a small town. It's just up to you whether or not you'll take him back. Remember, there is another option, but it doesn't sound like you are really thinking about it and if you are financially stable and would be happy to raise the baby then I don't see any reason why you would have to do it (but it is your choice, not his).
