QUESTION: My sister has a new boyfriend. She likes him. I don’t like him. He’s creepy. I don’t want to sound conceited but whenever he is over our house; I get the feeling that he is more interested in me than in her. Should I mind my own business or say something to her?
ANSWER: You owe this guy nothing. You have a right to set personal boundaries.
As far as possible, minimize contact with him. If he leers at you or tries to befriend you, ignore him. In private, tell him once, once, that you aren’t interested. No further conversation needed.
If the contact escalates to inappropriate conversation or any touching that you are uncomfortable with, you have a different situation. Tell your sister. She may be angry at you in the short term but in the longer term, it’s obvious that given this guy’s character, she’ll learn that you were right.
