c1t- I don't know if what you did was the right thing. But, i have to think that there has to come a time when you stand your ground. My psychiatrist told me, several months ago, that until i demanded respect from my H, there was probably little chance for us. And, he made a good point. We have to respect ourselves, in order for them to respect us. Letting him run around Thailand, getting pampered by other women, is a bit much. I think it was perfectly okay for you to tell him what you said. B/c how can he honestly work on things with you while he is off doing god knows what with other women? Doesn't really make sense to me.
Anyway, thats my 2 cents. Don't beat yourself up over it. There has to come a time when we set limits on how much we are willing to take.
