need help here....please!!

On a summer trip to the UK, I met a Lady at a swinger's party and we "hit it off", really well. I invited her to visit here (US) and since then we have gotten quite serious. My problem is that she has already told me that she wants to leave the lifestyle, if we become a couple, and I'm not certain if that's what I want. I'm a single guy and have enjoyed swinging with couples or Married Ladies a lot since my divorce and am in demand at parties, NSA sex has meant a lot to me, to help me "rebound", from my marriage, and I'm comfortable with it. She, on the other hand, says NOW that she was only in the lifestyle to partyand that she has no interest in pursueing it as a permanent situation. Is it possible for a swinger to go back to a vanilla life and be happy and satisfied?
