LettingGo, you make a lot of good points and, to be honest, I have been thinking that I have no intention of getting involved with anyone else until i feel that I have really worked some things out about myself, the marriage, my upbringing and until I have given myself time to heal (in anycase, my S is already dealing with enough crazy with his D - the last thing he needs is his M bringing a new man into the equation any time soon). So a fast divorce (although it seems to be what H wants right now, probably with some pressure from OW) is not something I really want to pursue.
I am moving to a bigger city though because I need to get work and have support of family that live there, and it will make our separation more pronounced - I know that they say "absence makes the heart grow fonder", but they also say "out of sight, out of mind."
Staying here is not an option though, I simply can't move forward, get the career I want and make significant changes to myself in this small town. I feel bad because it means changing schools for my S and also seeing less of his D, but frankly, the way H is at the moment, I am not sure that is such a bad thing. He is preoccupied with OW (infatuation) and even S said, " I wish D would stop talking about "OW's name" all the time". Bearing in mind that S is not even in Grade 1 yet and H moved out less than 2 months ago, I felt even talking about her with my S was inappropriate this soon.The pre-MLC H would never have knowingly and deliberately exposed my S to this much emotional upheaval in such a short time.
