A word about having an affair.
When in a long term SSM one tends to "look around". A couple of years ago I used to chat up every woman I liked the look of. I didn't know the technical term then but I was looking for an HD. Eventually I found one and became enfatuated with her. W found out about OW (I told her) and my fling had to end - I couldn't face losing my children (or W). The trouble was OW didn't want it to end and wanted to stay friends (so did I really) and it ended during it's euphoric phase. It just ended while I was still on a high. The trouble is I am still on the high deep down (and wondering whether she is too) so my advice is don't look for another woman if what you really want is your W because you will probably mess yourself up. I still feel her magnetic pull.
