Corri, I get what you're saying and it may come back to the love language concept. Since your LL is not physical touch, it makes sense that you would feel more betrayed by the marrying thought rather than the sex thought.
Myself, though, I would feel just as betrayed at the sex thought, since this is how my mind processes "love".
However, the whole point of the convo was to say that I am no longer in the obssessive hysterical jealous psycho-beotch mode that I was once in all day long. So while I do not mean to sound cavalier, it is also true that I just don't feel psychotic over "thoughts" anymore. Or at least not that much. I'm still a chick, after all.
