Hi Sister Scorpio!
A few things I saw here... Freelove touched on one already.
Don't fall into the mental trap of thinking that you don't have time for dating and relationships in grad school. And since our topic here is "black women," I'm gonna go there for a second...
Black women are the ONLY group of women that I hear saying this. This idea that dating/relationships are supposed to wait until after one's education is complete is a foreign concept to a lot of other women -- shoot, some of these privileged white and Asian women will flat out admit that they're in certain grad programs (like an MBA program) to get that MRS degree... and a whole lot of 'em get it too!
Meanwhile, we get in these programs, get our degree in our late 20s/early 30s, then want to play catch up. I'm not saying we necessarily have to be seeking the MRS degree, but if we know that we want a husband and family in the future, then we need to make time to have relationships, just as we make time to study and prepare.
I think too many black women are shooting themselves in the foot with all of this waiting, and a lot of the dating woes of the uber-educated 30-something set are a result of faulty teaching from our families about delaying dating and relationships.
And on another note... and this also goes back to EccentricRed's post as well... why haven't you wanted to date the men that were interested in you? Was there something seriously wrong with them?
One of the best pieces of dating advice I ever received (which is probably why I have a fiance' today) was to stop worrying about the men who didn't want me and start paying attention to those who DID. So, if a man asked me out that was reasonably decent looking, smart and kind, I accepted a date. I didn't care about my lack of attraction at the time or the fact that there was no chemistry or anything... I just accepted dates and then let the men who liked me continue to "compete" for me. After a while, I discovered that I kind of liked one of them...
If I had been thinking about dating at age 30 the way I did at age 25, I would not have given my fiance a chance after the first date. And that would have been a very bad decision.
