HELP! how can i know if my "friend" is really a friend or out to get me HELP!?

if you really don't wanna be friends with this person then you don't have to be. Just stop talking to this person and hang out with other friends a lot more. (And about how you're other friend got in trouble with their parents, i don't think a person's parents can really force you to be friends with someone you don't want to)
