Joss- glad you have found this board but sorry you are in this situation. I am a little over a year post BD and have very limited contact with my H.
I too stayed at home for many years. I work FT now and that has brought new challenges and rewards. I think my D's have been strong through all of this because of my time at home.
I wish I had found this site earlier but the more I start to understand MLC the more I realize that DBusting could not have prevented my H from choosing to leave. Don't try to to analyze because you can't rationalize the irrational. Just know that here you will find support, wisdom and the refuge you need from this emotional roller coaster.
Hang in there.
