<human>: I moved in with my (now ex) girlfriend in November and signed an 18 month lease.  It was the biggest mistake I've ever made in my life.

So here is the situation:  We're bound to a lease that is going to be extremely hard to sublet due to the building we live in having perks (free months) for people signing new leases.  It will be a nightmare to sublet.  I'm broke and can't afford to get my own place and neither can she.  Right now the only option seems to be to save money for the next 12 weeks (we have 2 months here that we don't have to pay rent) and try to sublet it after that.  There is no possible way I can afford this place and a place for myself.

The environment in the apartment is awful.  She's dealing with the breakup by sleeping with someone every night - and in the event that she can't find someone to go home with she'll drag her drunk ass home and try to crawl into bed with me (I'm sleeping in the living room).  I have to carry her to her bed and then she'll tell me she has no recollection of doing it.  It isn't acceptable, I've told her this, but it keeps happening.

I don't have any family or friends here (well, no friends close enough to stay with).  I've maintained strong relationships with my friends from where I grew up and gaming with them has been the only thing that keeps me sane.  I haven't been able to fall asleep without drinking myself to sleep since the breakup.  Being stuck in this apartment is killing me.

If anyone has any sort of advice for dealing with a situation like this it would be very much appreciated.

Provide a brief overview of the text.
