I’m sure you feel concerned that this guy is going to win her over, but I think that rather than addressing him, you should just make sure [i]you[/i] win her over, so she isn’t interested in dating anyone else. 😎 There is always going to be competition, and you can’t go around beating up any guy who likes her. But you can be the boyfriend she doesn’t want to lose, so she wouldn’t jeopardize the relationship. That’s a much stronger position for you to be in. 😉
