<human>: Condense the text into a few key points

This guy who I've seen around at school a lot and I chatted about a mutual appreciation of a suit and tie, and ever since he has assumed we are great friends. He's a really nice guy, but he is trying way too hard for a legitimate friendship to happen, instead of letting it gradually develop overtime as it should. He now sits with my friends and me at lunch without being invited to, and makes a good amount of situations uncomfortable. All he talks about is clothing now and boring conversation topics, and is way too "high-fivey" all the time. Sometimes it feels like he is coming onto me in a sensual sort of way, and it is just weird. I've been distant and uninterested so he gets the idea but he clearly hasn't. I don't want to hurt his feelings but i need to let him know i don't want to really talk to him anymore
<bot>: Guy thinks we're friends over one common interest, is nice but I can't seem to get rid of him. Don't want any hurt feelings.
