DS & GF are both 16 and have been best friends since they were 12, this more recently has blossomed into a romance.
GF lives about a mile from us with her mum and younger sister, her dad lives about 40 miles away. GF mum has long history of mental health issues, diagnosed personality disorder, takes a lot of medication. Quite often no food in the house, sleeps all day, has been arrested in the past for drunk and disorderly, brings a string of boyfriends back over the years - you get the picture.
GF relationship with her mum has always been strained and according to GF her mum has lost it completely and suddenly decided she no longer wants GF to live with her, bagged up her stuff and told her to get out. We thought this was just an outburst but the mum is completely serious, has arranged to move to a different part of the country and told GF she doesn’t want any contact.
GF dad has said she should go and live with him but she starts college next week which is on our doorstep and if she lives with her dad has no way of getting there.
I’ve come home to find she has moved into my sons room, I asked what was going on and they told me everything going on and they were both really (understandably) upset at how GF mum has behaved, she has also called my son names and banned him from her house (I’m not aware he has done anything).
I like GF very much, the mum sounds neglectful and abusive. I’m not really sure what I should do? I can’t see what I can do other than let her stay at our house mon - fri for college then see her dad on the weekend? What would you do?
