My Son has been brainwashed to go to his Dads

Quick Summary. My eldest 23 is at Uni and home on summer break and I let her stay at home. When I asked for help in relation to bills/keep etc they kicked off and went to live with their dad but convinced my 13yo to go too. The problem is. He has instantly stopped all money and not updated me on how long he intends to keep him. He works full time and feel my son will not get the care they need like travelling to school etc. The major problem I feel is that we havent even sent a petition order in yet and been separated for a few years.
Where do I go from here? I am in despair. Anybody been in this situation? Thank you

OMG I so feel for you.
I have no advise to you but just to say just be consistent with your boys, don't slate their dad.
Things will work out in the end.
My son is nearly 18 and moved out with me when I left my ex. His dad has completed slated me, nasty comments, untruths the lot, he has made my son feel guilty for living with me. My son didn't have a good relationship with his Dad before we left, despite his Dad's attempts to break our son/mum relationship he has failed. My son still feels guilty. Throughout this I've bitten my tongue, remained calm with my son when he has come out with all the lies his dad had been feeding him. I will not lower myself to his dads level.
Divorce/separation is very difficult and mighty stressful. My counsellor once said to me remember you aren't a victim you are a survivor! Which I repeat to myself when I've had enough.
all the best.

You need to figure out a way to get your youngest son to come and live with you at least part time as it will have major financial implications for you.

You ought to contact them to find out what is happening with regard to travel to school etc and also because if your son is going to live with his dad you will still want him to spend time with you as well.

You'll also need to sort out the financial arrangements.

Hi,
There are several things here,
the first is that you need to speak to your ex regarding what is going to happen going forward. How long has it been since they left ?

What were the care arrangements beforehand?

Have you had any contact with your son since he moved out ?

With regard to money, it is probably best to not focus on that for the moment, your ex stopping payments is reasonable, as would he asking you for child support. I assume that currently you have an informal arrangement.
