hmm.yapss.you have a "friend" that is only being with you for a reason besides friendship, and you want to break it off with them. It'll take some time, but in the end you will be free of their false friendliness.i give u 5 steps for u. so lets check it out..
1. Find out why they're doing it. Are they trying to climb up the social chain? Trying to copy your homework/work? Using you to get to someone else? Trying to find out some information? Why are they faking the friendship with you? You can ask them straight out, or just snoop around until you put the pieces of the puzzle together.
2. After you find out, see if you can disassociate what they want from yourself. They might just leave you alone after they know they can't get anything from you. If it's homework, just say you won't let them copy you. Or if it's a group project that you did ALL (or most) of the work tell the teacher/boss they didn't do their share (go to the teacher/boss afterward if you don't want to seem like a snitch). Or if it's a person, keep contact with the person while the fake friend isn't around.
3. If you can't disassociate, distance yourself from the fake friend as much as possible. Try to avoid them, or if you have a near identical schedule stay away from them as much as possible. When they ask to hang out say "No" or "I'm busy", eventually they'll get the message. If they, don't straight out tell them you don't want to be friends with them anymore.
4. Try to get 1 or 2 (real) friends that know they're faking to join up with you. Not against them, but if they try to get one of you guys just say "Oh, I'm -insert excuse- with -real friend-", and the same for your friends, let them use you as the their excuse. If the fake friend tries to join you two on your fake plan say you guys just need some alone time to catch up with each other.
5. If all else fails, plain out tell them you don't want to be their friend because you know it's fake.
