So my question is, does you fiance know that you are pregnant by another man and is he ok with that? I agree with QueenB in all that she said and I want to add that it is natural to feel a very strong bond with a person who has a part of themselves growing inside of you...I still have a love for my two oldest kids fathers even though I am not with them anymore nor would I EVER want to be again. They took part in making my children, they gave me something that no one else ever could, I see them in my kids faces, but one of them is a total deadbeat, I am now married and the other one is about to be soon, it is not a romantic love that I have for them though, it is a thankful love that I cannot really explain. It is possible that this could be how you feel for this other man but you need to really search your heart on this one, you do not want to commit to marriage and back out, you are having a child with this other guy and he is now in your life forever unless he wants nothing to do with baby and signs over his rights and even then he could pop back up if there is a medical issue down the road...This child is a precious gift and you are really going to enjoy being a mommy, just take the time to sort out the man issues, and pregnancy hormones may not help that process go any easier, maybe it is a time to take a break and focus on your pregnancy and then when the time is right you can discern who you truly love and want to commit too...I hope this helps...congrats on the little bean...Love Meg
