yes, your roommates aren't turning out to be true friends and as you are sober longer, you will have less in common with them.....them trying to set you up to fail is immature, unkind and cruel.
you might be surprised at yourself that you might not even enjoy the keg party and watching everyone get snockered....and you and your GF can leave anytime and do something better and more fun.....sober....
think of all the extra cash and less debt you will have from not buying booze....you can start up your housing fund again too!
there are a lot more positives to discover, I'm just saying.......good luck!!
