I guess I'm a lot less conservative than jharrison... I'm 24 now, I had lived with my gf very happily for 5 years, so maybe I know where you are coming from. I know tons of people who live with their gf's. Generally, I think living together is a good idea - with one important caveat. Sometimes, you don't really know someone until you live with them; and that goes with gf's as well as any other kind of friend. It can make you or break you. Here's the caveat though: (even though I didn't follow this, I wish I had), I say that you should only live together if you are seriously considering marriage. Heh, and no, not for religious reasons. It's just what you, *ahem* we, are so young. Living with someone is a pretty big step - your lives will essentally consume each others. It takes the relationship to a whole different level, and you have to consider if that's really where you want to take it. And once you decide, you're de facto very committed because now they live with you. And let me tell you, breaking up with your live-in gf is a nightmare from the deepest depths of hell. You thought ending relationships was tough before? You have no idea. Get my drift? You probably already have a good gig. If she hates her place so much, try finding her a roomate somewhere else. Since you already have your own place, let her stay over as much as she wants - so that she is essentially living with you but is paying rent somewhere else. That's all the benefit without actually having to move in. Yes, I know, it's a waste of money, but I think that IS the way to go... Sorry about the rambling, I hope this made some kind of sense. Whatever you decide, good luck. I'm sure it'll workout for the best.
