We hang out in a group:
I hang out one-on-one with these friends:
INFJ (6 months)--broke up because she "just wasn't feeling it", basically
ENFP (1 month)--apparently we were never in a relationship...?
INTP (long distance, 6 months)--the same friend mentioned above. She and I have a deeper, more profound bond, I think. I love that I can not call her for a month or two (nowadays, not when we were going out), then pick up a conversation with her and she's fine with it.
**And of course, the typings are just guesses.
My roommate in college right now is probably also an ISTJ. We give each other our quiet & privacy, and hardly ever talk, but I think we're fine with that (don't know for sure because I haven't asked him).
