I'm currently living with my brother (due to an abusive ex). He went out last night with his friends and he clearly 'pulled' and he brought her back with him. DD just wandered into the kitchen to find said girl making herself breakfast apparently with dbs permission (he's still in bed).
This scared her and she's been through a lot in the last month and having "strange women" in the house will not help this.
I know its his house and we are staying here rent free and he has been a saviour in what he has done. AIBU to ask him not to bring women back.
