I stupidly got pretty heavily involved with an escort, I need to get her out of my head. Any suggestions will help

I may have ruined a long term marriage by seeing escorts, we have our problems but at this time my wife and I are trying to create a "new " marriage. My problem is this, I met an escort over a year ago and ended up seeing her exclusively. The sex was great, she is stunning, but, after spending a good deal of time with her I know she has "issues". Problem is no matter how I try to "reason" myself out of thinking about her I can't. I want out of this self created hell. Any advise will be appreciated
