Sounds like your emotions are sky high, with the 'thrill..' of it all, I have foold around on boyfriends too, and it's almost an addiction, a sexual addiction, an emotional addiction, all wrapped up into one...there are consequences to your actions though, like the loss of your marriage, it IS possible....hard to fathom in the THRILL of it all...

How about some counseling for yourself too, also there are 12 step groups for sexual addiction.

Try to calm down somehow, but don't be too ashamed, it happens to many...
