Long story short, my partner has children with his ex. I've been there for the majority off the youngest ones life and just recently she's been diagnosed with cancer.
Since then, the ex has been on the go constantly, she sits in the house all the time, speaking to my partners mother, asks them for things/support/advice before she asks her own family.
She's always had an on/off relationship with me, liking me one day and hating me the next and just after the child was diagnosed she sent me really nasty messages that there were absolutely no need for. I spend a lot of time with these children as I often have them if their dad is away.
She was never as close to some members and now she's texting them asking for nights out and wanting to meet up and I feel as though she's just rubbing it in my face. She also has a really bad habit of trying to tell me what my other half is doing to my face, as if I'm not meant to know.
She texts my partner constantly, through the night and Half the time it's not even about the kids. She has a partner too so there shouldn't be any need for it.
I know I may sound selfish but this woman has made my life a living hell since I got with her ex and now it just feels as though she's digging her claws in!!
Help advice please? X
