My 17 year old daughter has a boyfriend that she really likes and we really like. He does not go to her school. However, she has started hanging out with another boy that goes to her school. He is younger, and not nearly on the same level socially as my daughter or her boyfriend. She texts him, snapchats him all the time. She claims they are just friends, and I do think she truly believes that, however I don't know if he believes that. I also do not like this boy- he drinks, smokes pot, and doesn't have a great homelife. My daughter is a major athlete and does not do those things--yet. I've tried talking to her about it, explaining that there is such a thing as emotional cheating, and even gone so far as to delete his snapchats if I see them come through, before she sees them. I don't want her leading him on, I don't want her getting a bad reputation and people talking about her behind her back about how much she hangs out with this guy, and I don't want her losing her good boyfriend over this boy that only spells trouble. Any suggestions on how to get her to cool it with this guy?
