Well....aren't you selfish 3 CHILDREN and Your Other Half, Your RIb, Your Children's Mama !!! I can't believe it !!!! Who is this chick your engaged to? She's not a good person to wreck your home, and split your family, If she will do this, what else is she capable of? Both of you are selfish, two selfish people wont make it for long. Of course you'll wait til after Christmas, what kind of question is that? think of other people for once ! You are making a big mistake if you dont breakup with that homewrecker, (no I'm not married never hv been) Your fiance should be ashamed of herself. You should break that engagement, and be true to your wife, and be there for those kids, children ALWAYs feel they were not good enough for Dad to stay. Beg the wife's forgiveness, break it to the mistress gently after Christmas. Seek Marriage Counseling. Grass aint greener for long, Winter Will Come. Trust Me.
