Hummmm..... if he's so sorry and repentant at this time, why wasn't he sorry and repentant about misrepresenting himself and doing something he knew would profoundly hurt you even more than than you've already been hurt? Wouldn't he have stopped earlier if those had been his feelings? It sounds to me like he's only stopping (?) because he got caught one more time. Also, if he feels this way because he's about to lose you, does that mean this is the only way to keep him from straying? Does it mean you have to always keep one foot out the door?

I think your husband probably does feel very badly, but the situation reminds me of an alcoholic who can't quit and has to sneak a drink. People like this do feel extremely sorry. They vow to quit and have every intention. But sometimes they can't.

I pray you stay strong and love yourself. Never let happiness be dependent on others.

There is no arriving, ever. It is all a continual becoming.
