<human>: Summarize the given text in a few sentences.

I study full time as a 24/M in graduate school. This isn't to say that I don't work hard at my academic career but I do have more personal freedom than my peers who work full time jobs and have careers in private industry. I recently was sleeping with a 24/F who has a career and our schedules really did not mesh well. Even in her free time during the weekends she was habitually too busy for me (they're always going to bars, seeing other friends, etc). I have found this as a repeating pattern with women in my age bracket. They lose interest at the junction of having to decide whether to spend time with me or with not-me. Admittedly, I do not like going out all night. Casual drinks until 12 is fine but this routinely is criticized by these women (21-26 year olds). Habitually it becomes a clash of schedules (or so they say) where I'm free when they are working or choosing to go out with their friends and then the rest of the time they are busy. Is this a passing phase? Are they just not interested in me after getting to know me better? Am I really an old man in a young man's body with no hope? My social skillz are at least one standard deviation above the mean for my field and while I'm not exactly a people-person I have friends with whom I do social things with and people generally find me charming.
<bot>: A girl broke it off with me because I don't like going out drinking until the morning and she won't make time to see me. It happens time and time again. Is it me, them, or both?
