How much effort do you put into dating as a guy?

r/

Im curious in terms of hours per week are you putting into dating? I currently have a gf but we are not in a good place. We may break up due to use truly just being different. Nothing happen that was weird just that I am becoming a doctor with a different personality and she is a teacher with her personality.

I used to be into cold approaching and going to bars. But as I get older(27 now) I get turned off when i have to try to convince a girl to like me. Now I am just pretty much willing to tell her no and set boundaries. As a result, I barely have female friends and dont get anywhere in interactions other than how is it going?

Realistic if my relationship dont survive, how many hours should I be putting in being in med school and what should I tolerate.
