Hi Aud,
Just read your sitch. I'm sorry that you and your H are seperated, especially with 3 little ones.

I think the best thing to do is GAL. Do everything and anything to keep your mind off of your R (or lack of R), cause if you are like me I obsess about it 24/7. It doesn't really help the sitch and only causes me to become emotionally drained, angry and frustrated.

It also helps to stay positive for your kids sake, even though they are little they can pick up so much. Last year around this time when my H was heavily into OW I was very bitter and angry and cried ALOT when he didn't come home. My oldest D's grades suffered tremendously and my younger two became very insecure, especially the little one; he didn't even want me to leave him at preschool for fear that I wouldn't come back (like Daddy).

Take care of yourself most of all!
