I dont understand the car leasing part, he either wants to R and earn brownie points or this is a way of him shedding some guilt. Just tell him right now you wont be able to cover any of it, so if he can pay all the lease amount you will be fine. Hey its not just for you he is doing it for his own D too, and from what I read you have put your life on hold to get him thru med school and he is doing well for himself now. And remember until the D he is still your H, WAH yes but still married.

It is great to read you feel so confident and grounded. It put a smile on my face to read that, you are not only doing this for your own good but also setting an example for your D.
