text: NO!u will end up the bad guy.best u can do is try talking 2 them seperately but if this is the way they have been 4 years it probably will not change anything.I have a sister who has been in a abusive relationship 4 over 30 years everything we did 2 help her only caused her 2 stop talking 2 the family an cause a really wide gap between us.I actually stuck up 4 her and beat the crap out of him.she has not spoken 2 be in 10 years.
