So I have this friend at college who no one else likes, and he actually drives me crazy most of the time. He follows me to my car after class even though his car is in the other direction, he's irritable most of the time, he makes inappropriate remarks, and he makes other people feel uncomfortable. I'm not even sure that I like him. At the same time, he started hanging out with me when it seemed like no one else would. And I see just the tiniest spark of potential that he can improve his behavior. And a lot of evidence that he's been socially excluded a lot of the time.

He has a class with me tomorrow night. A bunch of us were planning to go out after class to celebrate the end of the semester. I thought, if I don't invite him and he finds out, he'll be crushed. Another person has already told me that if he's there, no one else will want to come. I've already invited him. Haven't heard back, but I put it out there. Should I not have, and avoided making everyone else feel uncomfortable? I mean, he is difficult to deal with, and I'll honestly be relieved I won't have to see him as often once this semester is over. I finally feel like I'm making other friends, and that apparently means having to choose between this guy and everybody else.

I know this isn't Dear Abby, but I didn't know where else to put it.
