Hello Aaag33: You know... unfortunately some people just seem to get off on cutting other people down. Who knows why? Perhaps your bf's siblings are genuinely concerned for you bf's future. Or perhaps this is just "sour grapes", as we used to say. There's no way to know for sure... unfortunately.

I can certainly understand how this kind of treatment makes you feel. It's just natural to want to maintain good relations with your bf's brother & sisters. But you can't control how they act. From my perspective, I think the important thing here is that you & your bf do whatever you need to do to make sure his siblings' rude behavior does not come between the two of you. I wish you both well...
