My brother is only 21 but his childish, selfish behavior
truly stuns me. He's been dating a very career focused chick who is a nurse making good money. He's in med school and wants to be a surgeon, yet doesn't seem really serious. Right now he has a cushy research job at the biggest university in the state thanks to his gf's sister recommending him, despite him having no experience. He sister basically told him he's apart of the family and wanted to help him out; she's very keen on the idea of him becoming a doctor.
As I said his gf is super driven and rather serious, whereas my bro is lazy and very junky (messy room). She's been dealing with all that shit...and now he has decided he wants to dump her for no reason. Basically he wants to meet other people/fuck around.
The problem is that he plans on keeping the job, which strikes me as a douche move. He'll have to see the sister every day, too, which will no doubt be awkward but he doesn't give a fuck.

I'm not a fan of the gf but she's nice. She does everything for him BTW, including driving him around to various med schools (he's planning on transferring to a new one later). So it looks like he basically used her for a year and then threw her in the bushes...and he's completely oblivious that anyone would think that lol.
