Right. This has been plaguing my mind for a while so apologies if its a bit incoherent.
Have been with DP for 4 years, we have a nearly 2yo DS together. He has 2 children from his previous relationship 8&5yo.
His ex has been causing problems for a while, coming over with the kids to see their dad, which is lovely and I have always been welcoming, and on the premise of discussing the kids and care arrangements etc has told my DP that she wants him back.
I have ignored this, my DP isn't interested in her at all - she cheated on him for a few months before he found out and subsequently left - so I havent been worried that he will go back there.
Just recently there has been issues in her relationship that has meant we haven't had the kids at all for a few weeks - she was going through a messy break up from the guy she cheated on DP with - and wanted to keep all her kids with her. DP said it was her decision, And that we would be happy to have all the kids if it would help her out. She said she would get in touch to rearrange.
Fast forward to a few weeks later and I see her at the school gates. When I asked where her younger two were, she replied that they were with their dad (her ex) as 'at least he wants to see his kids'
This probably upset me more than it should have, but I didn't say anything. Her new partner apologised for her later on, but ex never apologised herself.
A couple of days after this, she came round again while I was out and told myDP a load of lies about one of my friends owing her money or something and that she was pissed off I was friends with her. Again, I didn't say anything at the time because she is not above using the kids as a weapon and refusing to let DP see them.
She saw me later and I blanked her as I did not want to be two faces, she later sent me a message asking what she had done wrong so I outlined it, not blaming her or getting ott about how I felt so that I wasn't picking a fight iykwim. She flew off the handle, and I left it.
She came round yesterday with the kids when I was at work and told my DP that I had cheated on him! He says he doesn't believe her, but it's going to have sowed a seed in his head and eroded some trust seeing as his last major relationship ended due to cheating.
I am so cross I just want to let rip at her, but I also need to keep the peace for the sake of the kids. And I can't trust her to be alone with him because she is so poisonous.
I am thinking of going to see her this week to find out what her issue is, but I don't know if thats a good idea or not? I am torn between confronting her, letting her get it all out of her system and moving on, or just ignoring the situation and refusing to let her in my house.
WWYD?
Thank you for sticking with me
