I feel for you and your child. My parents had a messy divorce when I was young, and they both tried to "influence" me for one thing or another, especially when it came down to whom I wanted to stay during the school year.

I just went through a divorce myself, and the one thing I kept in mind was what was best for my child. I can tell you first hand that the best thing to do is to talk to your child, explain the situation and your reasons for any decisions you make regarding him..you may be amazed at how much they actually understand ( I was 3 and I still remember it all). I would also advise you to keep your child's best interest in hand on all decisions, even whether or not you or your husband might be the best person to be with during the school year (since I'm not privy to all the information from all sides, I prefer not to comment or take sides).

Whatever your decisions are, I wish you and your son well, bless ya both.
