Yes this is very confusing. Like I have been told many times, you have to decide what you want. What will make you happy?
Have you read the DR book yet?
You might want to think about detaching. Live for you and your kids right now, not your H. Try to treat your H like a friend and have no expectations. This is hard because you are not used to treating him that way. Don't ask about the ow or bring up the R. I have learned the hard way. That doesn't help, it only hurts the situation.
The question about being on this board, was asking if you have your own thread and if it was on this forum (infidelity) or a different forum.
