I agree with the comments made so far. I also would rather be single and miserable (at times) than to be made miserable by another person during an important transitional point. I read the following post, and although I don't agree with all of it, I think it makes a good point: never sacrifice your ambitions for a (wo)man.
"An attending once told us about a resident he trained with who left residency because he wanted to spend more time with his gal. Turns out a few years later they broke up anyway. Talk about a double whamee...he gives up his dreams for a chick and she ends up leaving anyway. Never compromise your goals for a woman. Never. I don't care if she's tricked you into believing you've found your "soulmate" or any of that mamby pamby junk. They're replacable but they want to convince you otherwise. Christian Barnard [renowned surgeon] replaced them like every other month." "
