Heh, either that was a typo or you think really lowly of him.
I'm in something like the same situation now and I'll agree with you, it sucks massive amounts of dick.

Oh, and if you don't want to give up yet, try to call him out everytime he starts acting like a prick. At least you may get them to split up and give yourself a chance.
