Me and my sister's boyfriend just got into a huge fight and it's killing me to.see my sister crying over this!#!,

Her heart is broken ,he is no good to.Her treats her sooo.bad and not to mention cheats on.Her with just anybody that has a vagina in.between legs and my sister don't deserve this at all!!! :-[

I'm 15 weeks pregnant and have 2 daughters and I want my sister around as much as possible (she also has.2 daughters),but if she stays with him I think it's time to.cut all ties with her and let her open her eyes by herself!!!!

Am I right for doing this????
