@knockedup,
I've a great deal of sympathy and empathy for you and your situation. No one likes to be in a marriage where you can't feel you can trust your partner - especially when you know he has cheated, LEFT your marriage and acted badly with deleting those texts. This man is STILL NOT acting trustworthy!
However, looking back at your posting history on A2K, you've asked this same question several times and have already received some excellent answers.

What are you doing now about solving or getting some help with this problem? Have you sought out marital counseling?
Don't allow yourself to be a victim IF this man is a serial cheater and has NO RESPECT for you or this marriage. Your married, but he is clearly not !
