@Nycindie, that's what I've been thinking about doing, though as of last week, might not be so easy. I spent one night with my girl during a period when D has his kids, and got rather clingy and pouty with me, and after some discussion it's sounding like he's open to me sleeping with women, but not so much me dating women.
And, after some of the things I have been thinking and feeling? I don't know that I feel comfortable dating two people myself. Neither of us have really reached any conclusions yet, but that's kind of where we stand. It's so very complicated... :-/
