she has asked i leave the house for awhile, should I? 4months or so, but will not committ to going to MC or retrouvaille...etc
In your case, I think it would be appropriate for you to agree to live elsewhere for a while. You are the one who cheated, more than once. Show her respect and consideration by allowing her to remain in the home.
BTW, you said that you got in some sort of legal trouble related to your chat activities. What's that about?
