JKS, I've been living with my H's PA since last August. Focus on taking care of yourself. I love the advice from gr8. It will take time to heal, let yourself feel the pain, and you will grow from it.
I've decided to separate from my H and along the way I've met new friends and a new guy. Not really ready for any type of serious relationship...but you are young and you will be happy again!
I'm really in a place now where I've detached and I'd rather be alone than dealing with H and his issues. If he ever really had an awakening...maybe I'd try again. For now though, I'm not interested.
Hang in there...it's taken 7-8 months to get where I am.
