Can I tell my SO she needs to disassociate herself slowly from her low quality friends?
Why are you telling your SO to disassociate herself from her low quality friends?
I have been telling this to her for a while, but she's always getting drunk with them and coming back home a mess.
I can see how your gf coming home drunk to you could be upsetting, but it is impositional upon her to tell her not to be with her friends because of it. Let your gf make her own decisions about who she hangs out with.
But I want her to be my gf. It's affecting our relationship.
It is good that you care about her well being but at the end of the day you have to understand you cannot control what she decides to do.
