I don't know what to do !
My niece has been living with me for 2 years ( not in the UK) , she used to be very very difficult , anger ,drugs , skipping school etc... She moved in with me and now she is almost 18yo. Her mum visits us maybe once a year.
My niece is really now a really kind and nice person. Works hard , thankful , gentle. She , herself, can't even believe she used to act like she did.
So about 2 months ago , she started talking to a guy on facebook. She told me about it and is really happy about it. We had the "be careful" convo. She told me that he was always making up excuses not to meet.
My sister has a hard time believing that her daughter has changed , and always tell me I am just trying to find excuses. I once told her again how her child grew up and now is not who she was. After I mentioned the boy , she told me " I am veryfing what she is doing , X is really me. You'll see she hasn't changed and will show all the sex convo we had"
I am disgusted. Now what do I do ? Tell my niece about it , risking to ruin her already fragile relationship or just rell her he's not good to convince her to stop talking to that "guy" ?
