I'm against some of the advice in here and kinda on board with Pete. Judging by you putting up with someone as douchey as bluetooth guy seemed, I think you need more confidence. You're busting your ass 80 hrs a week and making good money. You have a quality education. Don't worry about getting some guy to like you. Be a strong woman and find some guy that can get a long with that. If you're working 80 hrs a week, anyone without the ability to handle a strong woman probably doesn't have the confidence to handle you working around/with other guys constantly.
BTW, people getting real serious and married in college is a very midwestern/small town thing. You're away from that now, you're not behind schedule or anything. Don't be worried
