So some back story first.

My partners brother has had two kids with this girl I used to be friends with in my younger teens. We stopped talking after a falling out between my partner and her.

She got on drugs dumped the kids off with my brother in law and h3 had to come stay with us 3 hours away because she was attacking him and sleeping with all of he's so called friends and just constantly ringing and abusing him.

They ended up sorting it out à few months later and getting back together. fast forward a year later and my partners family are trying to convince us she has changed and that she is a great mother. I'm the type of person who takes a lot for me to give someone a second chance and to be around my own two children, the only reason why its so hard is because I seen what damage she did, her children were calling me mum and getting so confused. It hurt a lot!.

This weekend my partner has decided we will go for a day trip with the kids and he asked my brother in law if they would like to come. I'm going to be cival but I just got this off feeling in my tummy about her. She also used to try to flirt with my partner and always wear skimpy stuff and when I used to say I'm not comfortable she's like I'm just trying to show off my tummy after the kids!!

is this day trip a good idea? to have her around our children.. I haven't seen her in a while so I don't know if she has changed or not
