So I recently learned that my stepsister’s boyfriend is in love with me. We talk a lot together, and I know he isn’t happy with her at all. They have 2 kids together, a house and everything. I don’t know what to do, should I tell her? We get along very well together, he is such a good guy but I clearly made him understand that there is nothing possible between us if things aren’t ended on his side as I don’t want any trouble and I have a lot of respect for my stepsister. I would never kiss him or anything but he is really a nice man. What should I do?
