i had this shit, just give it time. it'll blow for a hot minute, but they'll realise this person sucks. remember that you and your friends are on the same wavelength, and that they'll probably come around. what also helps is venting to your friends what this person has done to make you feel that way. (i know you said you can't, but remember, they have a good chance of caring about you more than the person if you have moral and emotional high ground, if they've creeped you out.) i had a case where the person i didn't like drew a not so wholesome picture based off of a girl who led him on. disgusting. i told the guys, and they actually opened up with their own weird/annoying stories, and we confronted him POLITELY, key phrasing AS ADULTS, and it took him a few weeks to get the memo, but the key thing is, *he did leave*. it sucks, i am well aware, you gotta locate the motherfucking inner sanctuary to not crash out at the guy. but the hangouts will prevail. and it will get better. hang tight, i'm rooting for ya.
