First of all, I’m sorry you’ve had to go through this and get to this stage. Please don’t think you’re alone, theres a good percentage of us on the forum who have been in your situation.
I would recommend signing up to gamstop. Also, be honest with your partner about what’s happened. I know it will be hard, and it will probably loosen the blow considering he already knows you gamble.
Remember, the hardest step is admitting you have a problem, so the worst is over, and well done for admitting it.
As for your rent/Bill’s, could your partner help this month or get help from family or friends? Remember, if you manage to get help for your bills and rent to give it straight to your partner to pay.
Hope you’re feeling a bit better now time has settled, and I’m/we’re always here if you need to talk 🙂
