Your sister's boyfriend ever fall for you? Would you date your sister's ex?

If they've been sexual its disgusting.
I totally wouldn't risk my relationship with my sister for a guy. I guy can never be THAT good.
Me and my sister are likely to be very similarly raised which seems like the same problems would eventually arise anyway.
Not to mention the guy would probably only be showing interest in me because he isn't quite over her. That definitely isn't a good way for a relationship to start.
Please note I have a twin sister and a non twin sister and I would not go there ever.1
