SIL RANT

Tayaishaa • Married | 21 | Mum | Muslim
So my husband and I finally crawl into bed after putting LO to bed then I get a phone call from my SIL she's screaming crying in the phone I asked her what's wrong and she tells " give the phone to my brother or I'll kill myself" (she's 32 years old) 
I pass over the phone they were Talkong then he hung up.
She lives 1 and a half hours away and wanted him to pick her up and bring her here because her and her husband were fighting. (She has a car and licence) so husband asks me and I'm not one to get I between family issues so I said do what you think is right and I'll stay here with LO (6 month old daughter) so he leaves and when he gets there she says that they are fine now and he can go home.
Are you fucking kidding me?
This is the 3rd time she has done this to my husband. I told him that I have to put my foot down now. I'm 21 she is 32 she can take care of herself I'm no longer going to let my husband do this when every time he has he gets sent back. So childish! 
Ugh, it's 1am my poor husbands turned around and driving home now
