So then does the "keep it to one at a time thing" when physically involved, not apply to married people?
ouch... - no, it should apply then too. (if you're using me as an example, my marriage is something I'm trying to transition out of, though obviously that's not the best way to transition. Life is complicated) Anyway, even in this situation, you should keep it to a minimum, and "none" is really better.
I think its about 3 months...In the first month, if you make it that far, your dating, but there is no real committment...The second month, you start to grow attached and realize it could be somethign more...By the third month, you really enjoy each others company, and when introduced to friends, your exclusive... My girlfriend and I are exlcusive, meaning we don't see anyone but each other, which I prefer...I mean, I'm tired of dating around, she's tired of dating around, etc...However, I'm not sure how long the relationship will last, but will enjoy it for what it is for now...
