A friend dating another friends brother?

I think I’ve got my head around it – one of your friends is dating another friend’s brother? It’s not very nice if she is just using his to make her boyfriend (I assume ex-) jealous, but it’s not really something you should be interfering with. It’s nice that you are concerned and you can offer advice, but further than that it’s up to her.

If the sister is interested in maintaining a healthy relationship with her brother, she will mind her own f-king business (as should you). This is speaking from very direct and very relevant experience.

He can take care of himself, surely.

Is the sister also a friend of your best friend? All I can tell you is that If I knew for sure one of my friends was using my brother, I would find it incredibly disrespectful. I would at least give my brother a heads up, but let him make his own decision in the matter. Maybe that’s what she should do.
