I have had a similar experience. My ex thought that he could move his girlfriend into our home and they would live in the basement until our divorce and was angry with me when I kicked him out of the house when he said he wanted a divorce. I didn't keep the house, but stayed in it until I found a nice place to move to. I was in horrible emotional pain for a long time and was in counseling for over a year. My self-esteem was at its lowest for a long time.

I would give yourself more time. How long ago was the divorce final. I always heard you need to give yourself at least a year (more like 3 for me)before making any other type of radical changes in your life. Did you every read "The 5 stages of Grief" by I believe Kubler-Ross. A divorce does follow these steps (I wish I could remember them now, but it has been 20 years since my divorce).

More money in a job doesn't mean anything if you aren't happy with what you are doing. Your current living situation sounds so ideal, I would find it difficult to give it up.

If this new relationship is 'right', it will be there in six months or more until you feel sure you are ready to move on.
