Thanks for the quick attention. But some of my questions remain unanswered (at least fully).
1) To Saffie: Please don't blame yourself for what your spouse did. It was his choice to cheat. You can't make anyone cheat. And please explain how you can still love someone who betrays you? I just don't comprehend.
2)To PuppyDogTails: I assume from your post that your're a Christian. If not, I apologize. If you are, isn't it true that no less an authority than Jesus himself said divorce was permitted for marital unfaithfulness?
3)To Little Engine: I realize that the tone of the line you quoted was harsh. If it offended you, I apologize. That was me venting. But let me ask, isn't forgiving someone without demanding that they change just an invitation to more unfaithfulness? One thing my father taught me was that if you let people take advantage of you, you are in for a crappy life. I guarantee that no one will get away with that crap with me,ever, no matter what it costs me. Self-respect is absolutely vital. If you don't respect yourself enough to refuse to tolerate betrayal, you can't ever expect someone else to love you, because you must first respect someone to love them. No one loves a doormat. Pities them, maybe, but not loves.
Thanks, everyone. Please keep the reasons coming. And if I vent now and again, I'm sorry. I'd also like to hear from people closer to my viewpoint, if there are any. I just find it almost impossible to believe that there aren't more people who believe that the first priority of a betrayed spouse should be standing up for themselves.
