I think he is a jerk. She is aware of how I feel about the guy. After listening to me in detail, all she said was that it doesn’t matter to her. She also added that she’s in love with him because of his pleasant personality. I tried to explain to her that he’s just using her to get even with me but all my talk has gone to waste. It is as if he has cast a spell on her. Should I tell my parents?
If you are convinced that this guy is a jerk, you need to ring alarm bells. Are you convinced this guy is getting close to your sister to get even with you? Then you need to fill in your parents about what is going on. But you have to tread slowly as you sister is in no mood to listen to anyone. Remember she is in love, so she will not see any reason, even if you try to knock sense into her head. You have to take your parents into confidence and explain what went wrong between you and him. May be they are unaware of what is happening. But it is better to be safe than sorry — this is something your sister should realise.
