I'm struggling a bit to get my head around this. ExH and I split up several year ago. He was very controlling and manipulative and I initiated the divorce. During the divorce and afterwards I found out he had lied about the separation saying I had an affair (even telling my own family this) and in court trying his best to make me look like a bad mother. All lies! At one point I thought I was losing my mind and it took a very long time to establish boundaries/gain confidence again. I am now the primary carer. Despite all of this I could not bare not to see my children at christmas or birthdays so always invited ex into my house for shared birthdays and celebrations. My ex has been civil (and overly fake and friendly towards me) in front of the children and other people but still always criticises/argues with me in emails/text messages and has zero respect for me. I have tried very hard to maintain boundaries/be civil for sake of the children.
Since he started seeing a new girlfriend he has decided he doesn't want to do any shared celebrations and instead split birthdays and Christmas. In one way I think this is good because I hate being in a same room as my ex but I cannot fantom being away from my children at christmas or birthdays. I also feel a bit bitter as I tried so hard in the past to have these days together for sake of DC. Now he has a girlfriend he has decided he wants to split these days.
We didn't make any plans for DDs birthday which is in 3 weeks time. Today a friend (one of my oldest friends) messaged me to say my ex has messaged her about my DDs birthday party inviting her and her DD. Basically ex has arranged a party for DD while she is with him and is inviting the children of my friends to his party. This is the first I have heard of it and obviously I am not invited!! He hasn't spoken to this friend in years except at DD's party last year at my house when I invited her. She accepted as she thought I would be there too. I messaged ex and he said yes he is having a party and it's none of my business! Divorced parents having separate birthdays is one thing but isn't inviting my friends taking the piss? There are no boundaries with my ex. And what about lockdown?? I have only met up with a single friend in lockdown without my DC.
My sister also said recently she had some messages from ex via Facebook asking how she is and that he'd like to see her again. My sister thought this was a bit odd as she hadn't heard from him in years as well. I think it's bloody odd too. If he were a nice person it would be a different story but he's not.
So, basically how do I deal with this? This sudden contact with friends/family is weird and seems another attempt at somehow trying to control me. I don't know who else he has contacted about this party and I'm pretty sure he will not be mentioning to these people (and probably many of my friends) that I will not be there. It seems an attempt to push me out of my life which has happened in the past (he has actually stolen some of my friends from me and tried to push me and my family apart!). I realise this is quite complex as ex is highly manipulative. How to deal with this?
