My husband cheated on me with prostitutes as well. He stated that there was no emotional ties to them, and confessed to doing it 3 times. I have to agree with the escort lady, and no I do not blame any of the women in her profession; however, she has a point. He's lying to you and he's only sorry because he got caught. I'm hanging in there for various reasons, but do I trust him -- nope. Do I think he will do it again -- absolutely. Unfortunately, we are filled with resentment and sometimes express ourselves through the anger, pain, and betrayal that we feel. Be careful though, because if you want to stay in your mariage this will eventually push him away and probably give him another reason to cheat with whomever. So don't make any rash decisions right not, but DO YOU! Lord knows I am. My situation has brought a certain awareness into my life and I'm a much stronger person than I have ever been. Yes, I have set backs, but I am looking at the bigger picture. You can get through this, but never let your guard down. Hey, look at the bright side... at least he had common sense to use a condom.
Good Luck!
