(((((Kiki))))) OK, so now you know for sure that nothing is done and decided. So, don't go to begging, pleading, and all of that! He knows that you love him, and you are there for him. I don't think this is the time to tell him. Let him think about what he is doing.
Did I just hear you say that he knows you will cheat on him, because your mom had an affair, but his father having an affair doesn't enter into it? Someday, not yet, there may come a time to remind him that what your parents, or his parents did, does not control what you guys are going to do!
I think the though of having a baby scares him. That's not too much of a surprise. Take care of yourself, and see what happens as he adjusts to this reality!
