One of the signs is you friend is trying to get you to break up with your boyfriend. Also when ever you are alone together she comes in and interups you. If she is always laughing and "acting dumb" around him that's another sign. If she's trying to always hang around him and his friends that should be pretty obvious.

If your fiend is doing this then she's not your friend. You need to ask her what is wrong. If she likes the guy you're dating then you need to think "Is she going to get over him or will she stay like this?" You need to tell your friend that she means a lot to you but that your boyfriend does too. If she refuses to back off then you need to stop being her friend.
