Lily honey,
It's never us its always about them. I caught my ex cheating on me one to many times and I drove myself crazy gather all the proof even when one of the girls was on the phone with me and I was asking him about her, even when I showed him his emails he denied everything saying I am the crazy one. As Ann said it only make US sick to our stomach I had enough in January and walk away and thou I is hard financially ( I had to leave a good job I had recently gotten in DE to move back to Jersey and still I am unemployed but I am living with family and thou its not the best right now I am much happier)
Can't you stay with friends or family until you get on your feet? (I was suggest you read Women Who Love Too Much by Robin Norwood. )
