So this friend of ours has been flirting around with a lot of girls lately. First of all we dont like the way he looks at girls. It's like all he wants is attention from as many girls as possible. It started when he broke up with his girlfriend (a very nice and kind girl) in a very cruel way. Then at the next party he kissed a lot of girls - including my friends ex. His anger went at me instead, no fight so far. Then here, an hour ago he also went to second base with another friends ex. The problem is that he doesn't seem to know what he is doing. We are considering two things: Either we confront him, even though we know he won't understand or change, or we just freeze him out immediately.
