I have been married 3 times and each marriage has been horrible and I have been cheated on. Due to all these issues I have a very bad feeling and will not marry again. Why is it that people cheat? I do not understand. If you are that unhappy than leave the marriage before. My last one really hurt me. 14 years of marriage. He would not go to counseling and when I moved out he moved his 21 year old secretary in. Talk about a slap in the face. I still feel like a loser because of this. I keep telling myself that it is his problem but it still hurts.
