IMHO I belive you are making the right move. When they leave it's because they don't want to be around us. I wish I had gone much darker when W and I first seperated.
When you do have contact with him try to bundle any issues you need to discuss together (insurance, finances, etc.) to keep contact to a minimum. Be confident, happy, busy.
P.S. What the heck is it about this seven year thing?!?
