In the interest of science, I had sex with my now-husband on the first date and he (gasp) married me. He likes the way I look, but he thinks shared interests are more important.
I dress pretty conservatively. Do you think I tricked him? *interested look*
I'm also strictly monogamous. Who'da thunk.
Mojo, if the guy you're with is intelligent he'll realize your not a "slut" no matter how you dress, or when you have sex with him. Your personality and your track record are pretty solid. No, you'd probably not be a good match for a conservative Christian (neither would I) but you'd not be a good match for him in other areas, so it's just as well.
I personally think Burgbud's advice is pretty good. I also think Don may have a point that you'll have a much clearer head once you're legally divorced. Not for any moral reasons, but because all divorced people I know say that it's different to actually see it on paper. I don't mean you should stop dating, or save yourself, or anything like that, just cut yourself some slack. These things take time.
