Hi Everyone, I need your valuable experience again. I wrote last week about my ex NPD/BPD and sleeping arrangements at his new house. Since I stood up to him and let him know I was not happy about our 12 yr old daughter sleeping in the same room as her 14 year old stepbrother and half brother and the fact that our sons 15 and 16 have now be relegated to the sofas in his new house he has started to play mind games. Just to add our oldest son who is 20 and has Aspergers will now not be able to go over at all due to lack of space. Normally my ex comes over in the week to visit them for an hour. He used to have to come over on set days as per our custody agreement (usually a tuesday unless he texted to change the day)for many years, but as the children got older he started to make his own arrangements with them as to when he would visit. He works shifts so to be reasonable I turned a blind eye to his turning up when he felt like it. This was a mistake which I am now regretting.I should have challanged it the first time he did it but I guess I avoided the aggrevation of having a big falling out over it and also it saved me having to see him in person at the front door. Ignoring it has allowed him to violate the boundaries of our custody agreement and he of course enjoys doing that and being in control.
Anyway since last weekend when I told him that he was not having the children he has not been to see his children mid week as he normally does. He is also ignoring his oldest sons emails and texts. Our oldest son needs to know if he is going on holiday with his father, as myself and my Husband are going away next thursday and we need to make alternative arrangements if he isnt going to be with him.
He has also not been in touch with his other children to let them know when he will be over this week. I do not like this kind of behaviour. I feel his children and myself need to know his arrangements so we all know where we stand. The kids are kept dangling wondering if he is coming over or not. I wonder if he is doing this to be in control. My oldest son is getting anxious and upset because he isnt getting any concrete responses from his father about the holiday arrangements.
I have a feeling that he is being awkward and taking it out of them because of last weeks altercation and also he has just been reviewed by the Child support agency and will be paying more. I had informed the CSA that due to his extravagant lifestyle he must be withholding the correct pay information and that I understood from our children he had been promoted over 3 years ago. I think when the CSA officer called him up about the figures he might have realised somthing was "a foot" and decided to submit the correct ones. The reason I believe this is because the figure he will now be paying is a lot higher even though he has one less child on the claim. Unbelievably here in the UK they rely on the honesty of the fathers to tell them how much they earn unless an ex spouse/partner calls it into question. It is only then that they contact the employer for the pay check info. I only wish i had know that before now :'( I guess i have to be grateful as I know many parents do not get anything at all from their exs.
So what I wanted to ask is, why does he keep witholding information from his children and myself about holiday arrangements, times and dates? Is it control and because that gets the children/myself focusing on him ? how can I prevent him from hurting the children like this and what strategies work well in dealing with this kind of behaviour. I am guessing it is passive aggressive behaviour ? keeping people dangling/waiting and not letting them know when you will show up? He especially likes to do it on birthdays which as you can imagine is hurtful. Lateness is also something he does frequently. For instance if he tells the children i will be over in the morning he may well turn up in the afternoon. Or if he says a time like 10am he will usually turn up at 12. It is all very frustrating The next time he does it I am seriously thinking about going out so he will have a wasted journey. I dont know if that is a good tactic or not?
I am thinking to go see a lawyer when we return from our holiday and set some boundaries that way. I need guidance in knowing how this type of behaviour effects/ damages children and is it important to do something to prevent it. I cant seem to think clearly today and need some clarity Some days I dont have the strength to fight you know

Thank you in advance.
