My brother recently moved into a new apartment, after getting a job in a new area. He makes 50000 a year, not bad for someone who basically just graduated college, working as an IT hepdesk-person (not sure of the exact title). He started seeing a girl who lives on his street who he met on ok cupid.

She starts coming over pretty much every night for sex. Before long, they are chilling and watching tv together every night before sex, and last week, they spent two "sick days" together when they both had a cold, were they just watched movies and cuddled I assume. I've told him multiple times I think the relationship is going too fast.

Fast forward to now. They have started discussing going steady, but he found out a few disconcerting things. One, she has slept with a guy she regularly sees a couple times. Two, she has a matching tattoo with another guy she still hangs out regularly. I think shes still sleeping with these guys, in addition to him, and just wants to lock him down as a beta bucks. She currently works as a receptionist making 10 an hour, and has no real future prospects. I have told him such. They are meeting tonight to "discuss their relationship". Please guys, give me some good advice to pass along to my bro. I don't want to see him get screwed, I had a girlfriend like her years ago when I was in high school and don't want him to go through the same shit.
