Have Trouble With Boyfriend Sister

[latinprincess]

I Need Advice For My Boyfriend Sister.

She Is 20 With 1 Kid And One On The Way. But We Are Having Problems Her And Her Boyfriend (the Unborn Babies Daddy). Its Gotten To The Point Where He Wanted To Shoot One Of Her Three Brothers. Because They Waned To Beat His ***. For The Way That He Was Talking About Them And To Them. This Guy Is A No Good Sob. But She Still Wants To Be With Him. I Drove From My House To Bfe. Just To Go And Pick Her Up. And When I Get There She Decided That She Was Going To Stay. And Her Mom Was With Me. We Call To Talk To Her And He Wants To Pop Attitude With Mama. And Thats When All Hell Breaks Loose. He's Talking So Much **** To Her. And He Was Telling Her That His Friends Are Going To Be There Waiting For Her Brothers To Get There. And As Stubbord As She Was She Was Going To Stay There. When I Talk To Her I Told Her She Was Willing To See One Of Her Brothers Shot. And I Told Her That She Would Still Be With Him. She Never Said Anything Back. Well And Then Last Night She Called To Her Moms House And She Hadn't Called In A Couple Of Days. But They Both Call Talking Hella **** She Was Cussing At Her My Telling Her God Knows What. And He Was In The Background As Well. Taking About He Was Going To Go Over To Her House An Kick Someones ***. I Feel Sorry For This Dude If He Steps One Foot In The Yard. Hell Get His A** Beat. Not Just By One Not Two But Three Brothers. And I Understand What They Want To Do Because No One Disrespects A Mama. And It Got So Bad That Her Mom Told Her That She Don't Have A Mom No More. If She Was Going To Pick Her Ugly A** Boyfriend Over Her Own Family. So What Can I Do? Should I Just Let It Go And See What Happens Or Should I Do Something To Help?
