Relationship with bro ruined

I'll try to make this as short as I can.

My brother, his gf (will call her D) and 2 kids (under 2 at the time) moved in with us. They were struggling and we wanted to help; Make life better for my niece and nephew. They stayed for almost a yr. My brother has his own issues and D has been trying to plea with him to do better, talk to her, be more involved with kids, etc... And they never saved up enough to move out, due to his poor choices. And with my (and hubs) baby coming, we told them in January to find a place.

They moved out a month ago.. suddenly within a week. In with people they only met once. In a different state!! And needless to say, my brother went back fully to old habits and it is not safe for D or babies where they are at.

So we told the D to come back with the babies but my brother is not allowed in this home. D is on SSI and is young (24?) And my brother is 39; 3 other kids. One we never met and is nearly 13. Has history of mental illness, drinking and other things. Won't ever stay on the correct path too long.

But with all this said, I am worried for D and the babies safety leaving where they are. While I love my brother. I will not condone his actions towards those babies or D.

I am worried how we will all do when d and babies get here. If my brother will get into a drunken stupor and show up. My husband will not hesitate to defend them or us. Or if no one's home and he shows up when it's just D and the babies... And my husband nor I am there to defend her.

And I'm angry. While I know it's the right thing to do for the babies and D, I find it unfair I am now going to be helping the people my brother claims to have loved so much but again failed. Yes I say failed, he's done this to two other women. Our entire relationship will change over this.

And before I forget, D does not have family that will support her. All we can do is help her until her SSI person can help her find housing and such. But even with the little she gets, idk if she'd make it on her own. My brothers dad isn't involved with him. Never has been. And our mom is dead. Brother has burned other bridges with family too.

Just needed to vent. Someone to listen. Thank you
