MikeW saidSo, you don't like him well enough to be his friend?Well, the issue is I may like him too much to be his friend (i.e. still have raw feelings). I think it's disingenuous to dump someone, but still expect them to be your friend. What he is seeking is all of the emotional support, without the commitment of me as a boyfriend. He even went so far as to say, he would probably still rely on me for emotional support in the future.
Obviously you don't have to offer emotional support to anyone you don't feel comfortable with. If you feel he's being manipulative and passive aggressive, no, you can't be friends.
Getting "closure" to me means getting clarity. Sometimes that takes a while. Clarity is often clouded by our strong emotions. But if you feel strongly that you don't want to be friends with this guy, that's a pretty clear statement. A decision, even. Beyond that it is just going through the adjustment of not having him in your life.
