Nope!
I've gambling addicts in my family and my advice is get out and separate yourself legally and financially from him as soon as possible!
This is a betrayal, would you forgive a 10 year affair? I doubt it
He doesn't sound remotely aware or genuinely remorseful or willing to address his addiction, he didn't even tell you himself!
This is NOT just about the legal bodies that can pursue you for his debts such behaviour very often puts you and your son at risk from very unsavoury types because that level of addiction and debt rarely comes from purely legal and regulated sources. And even that's bad enough!
For starters do a credit check on BOTH your details and possibly your sons too (yes really) to check if he's run up debt he hasn't disclosed (highly likely)
Not even slightly kidding here.
But like my mum said my son will feel a lot worse when his father leaves us homeless from another mistake!
Your mum is right!
There are a number of mners who had gambling addict parents who's names escape me for tagging purposes right now but they will tell you how awful it was growing up with that financial uncertainty, bailiffs (or worse) at the door...
A relative of mine was abducted as a child and held hostage to make their gambling parent pay up!
He's not only put your financial security at risk but your personal safety.
I'll be AMAZED given what you've said if it's "only" £70k I'm betting it's way more! What's the house worth?
and my husband will obvs have to pay support absolutely don't bank on or budget on that basis, he's an addict he will prioritise his addiction.
The addicts script is so close to the cheaters
Deny deny deny
When caught only confess to what your accuser can prove
Gaslight
Non apology apologies
Pay lip service to "changing" without ever really intending to
Basically
DARVO - deny, attack, reverse victim and offender
Addicts lie, don't trust his promises
You need a financially very astute an experienced solicitor, possibly a forensic accountant to deal with leaving him
Re separate bank account - separate banking GROUP. Too or else they can access your account to pay his debts (unless that loopholes been closed?) I learned that one the hard way and ex wasn't a gambler!
