To each their own, but I have seen to many couples having problems and the husband or wife turn to an ex or "friend" and its innoccent at first, but turns into more. You here it all the time, the excuse is, it just happened. Well if you don't put yourself in a situation where it can just happen, then usually it doesn't. I once had a friend who trusted her husband and they had a great relationship. At least she thought so and everyone else did too. He went bowling with the guys every friday night and sometimes to tournaments over a weekend. Well bowling wasn't the only thing he was doing. She found out he had a girlfriend for two years.
