DS is 18 and been with his girlfriend about a year. He’s a very laid back person and too nice for his own good. He runs around a lot after his girlfriend, picking her up, driving her to places and most of the time he’s the one who pays for things when they go out (we’ve told him this isn’t on to no avail). Past few months we’ve been noticing more and more that his girlfriend makes fun of him. She’ll say something derogatory about his driving, what he’s eating etc. I’m well aware that I can’t interfere in their relationship but I have asked him about this and he says she’s just joking. His sister has just told me she’s been making fun of him a lot today on their way home from college. What should I do in this situation? I don’t want to push DS away.
