I am just not convinced she was over SM, or that a final break-up had happened, at least on her part. I am just imagining back to my own (naive/not smart) self at her age...if I had a "major thing" for a new guy, first thing I would do is thwart my current relationship in any way possible, i.e cause fights, make accusations, excuses to move out. And then if my friends were getting on me for seeing a married guy, I would tell them it was over and even accept a date with an old friend/acquaintance to "prove" it. But my brain and heart would be with married guy, and I would have run back at first call. JMO
