Husband and Divorce

My husband and I have been together for 13 year, married for almost 3. We are on the verge of divorce and things are not going well. He has always known he had ADD, but always thought if he tried harder that things would get better. I have been begging him to get help for years, and only last month did he decide that he did need help and started taking medication and seeing a psychologist after I told him that if he didn't do something that I would leave him.

The problem is that he quit his full time job right after we got married and has not worked full time since. He is not an equal partner in our marriage and I am left to worry about the bills, our house, all of the finances. We can't start a family or make any plans because of the situation that we are in with him only working part time for the past 3 years. I've tried everything that I can think of and things will turn positive for about a month and then its like he forgets and is back to his old ways. I feel like I am just beating my head against the same door over and over and nothing is every going to change.

He has definitely made progress in the last 2 months but I just don't know if it is going to last or if he is really going to be able to change. I don't know if I can forgive him or get past my anger and resentment. I have been trying but nothing is helping, any one have suggestions on how to get past this? He still does not have a full time job or the prospect of getting one...
