I'd have to agree with butterfly and ozzie. Cheating on both parts is never a good sign. It's hard to give up on a long term relationship. I'm in the middle of that situation myself right now. The thing you have to consider is this. Everyone has flaws. And there a couple of keys to a relationship. Off the top of my head are communication, honesty, and trust. It seems to me that each of these have been broken by both of you. Another thing is being able to live with the flaws of your partner. If you can't do this, then a lasting relationship is out of the question. I'd say that if you guys are fighting all the time and can't trust each other, then it might be best to just walk away. I know that's a difficult thing to do, but sometimes it's for the best. This is just my two cents. Take it for what it's worth.
