my SO shows up with his douchey cousin and they are both drunk, begging me to go to his sisters apt. it's already 8:30 my happy ass is staying at home thanks though. not to mention I hate this cousin because he asked me if my little sister whose 7 has "problems" I already can't stand the sight of him why would I want to spend time with them?! and at 36 weeks pregnant I don't want to be around a bunch of drunks. my son won't be raised around drunks so my SO better enjoy his alcoholic life for a little bit longer or get out of my life because I can't deal with it much longer.
