The fact that he is throwing money away gambling in his situation is utterly unforgivable.
I'm a placid person by I would be positively incandescent on that.
That fact, even more than anything else, shows how critical it is that you not give him more money.
Look at where he's at mentally - he's a husband and father with commitments and debts who has sponged off his wife and let her down repeatedly.
If he were actually interested in and motivated to change, and sorry for his failures, he'd be frugal and conscientious and diligently working away at his debt to you and others.
Instead, he's irresponsibly wasting money on alcohol and recklessly throwing more away on thrill-seeking gambling and now wants to 'borrow' yet more of his wife's money to continue doing so.
I had gambler/loss-chaser alarm bells ringing after your earlier post when you said he wanted a 'buffer' and still hadn't given you a full financial accounting, but forgot to write about it, sorry.
Personally, I would :
- Demand he request a credit report right in front of me
- (Quietly) Seek legal advice to determine what, if any, exposure I had with respect to his debts
- Remove him or myself from joint cards, accounts etc., and change all the passwords to mine
- Change my email password and 2 step/backup authentication, or preferably, set up a new email address for everything to go to so that he can't finagle access
- Then I'd be looking to move out as soon as humanly possible.
I'm in Australia so I'm not sure about what services there might be to advise you, perhaps other posters will chime in.
but you need to accept that he cannot or will not be the partner you deserve nor the father your child deserves, and start taking serious concrete steps to disentangle yourself from him.
I don't know what the answer is about this month's expenses.
If you'll be homeless without paying the rent and have nowhere else to stay, and can't move before it's due, then do what you need to as a temporary stop-gap measure, but only to give yourself time to line up your ducks.
But do not give him any discretional income whatsoever.
He can take lunches and coffees rather than buy. He can walk to work or arrange lifts. If that is utterly impossible, give him the train or bus fair daily, not in one lump sum - again, only to give yourself time to get organised.
He needs to feel the results of his behaviour, not be cushioned from it.
