Does he acknowledge he has a gambling addiction?
He needs to admit this and seek help.
I assume the problem is online gambling, it’s an easy trap to fall into.
The problem is, he needs to put more money on, to win what he lost 10 mins ago. And he won’t, there is only one winner and that’s the online companies/bookies.
Encourage him to ban himself from online gambling for 5 years, he has to do that in front of you in order for you to be able to trust that he has done it.
Encourage him to go to GA. The hardest thing is acknowledging there is a problem, the second hardest thing is to walk into a meeting. Go with him, and sit and wait outside in the car.
It will be hard, very very hard, but with encouragement he may be able to turn things around.
I know you’ve been in a relationship for a short time but can you confide in his parents, hopefully they can support him too.
Ideally someone needs to take complete control of his finances. He can have a bank card but the person who takes control gets notifications when he withdraws/spends anything.
Go onto I player and look for Paul Merton, football, gambling and me.
It is a very honest reflection of his addiction, it is thought provoking and it may help your partner understand why he feels the need to gamble.
If you love this guy, then support him, not necessarily financially, but support him to realise he has an addiction and make positive changes.
Addicts comes in all forms, some people are shopaholics, addicted to food, addicted to their phones, addicted to mumsnet, drug (prescribed or illegal) and alcohol dependent, addicted to sex.
It’s unfortunate that so many people have told you to LTB. I hope they never have to deal with a partner, child , parent or friend who sadly becomes an addict
Good luck with whatever you chose to do 💐
