Honestly I feel for your and your familys situation.
I think as things are there is actually very little chance of your husband actually succeeding in becoming a poker pro that can sustain himself/not even talking a family from what he does. The reasons are simple:
Bankroll - if his bankroll is constantly on the verge of having to climb down a stake it's probably affecting his overall attitude/mental state which is particularly bad for a poker player.
2 years without getting anywhere? I know it sounds like a harsh judgement but maybe he is doing something wrong / not learning the right things / or just is not meant to be a winning player?
To be honest I'd expect everyone who puts in the learning hours / game reviews and solid brm and table selection etc etc over a period that long to be a solid NL50reg at least (even though it's probably the most reg infested stake out there atm). And of course knowing that he hasn't gotten anywhere during that time will affect his mental state even further. Then again idk how many tables/hours your husband plays? Maybe it's just a volume thing...
Last but not least, living on the verge of bankrupcy is not really a great spot for one to be in when you actually want to draw out your own potential to the fullest.
My advice for you and your husband: Lay off the poker for a while, even in a country where work is hard to find it's still going to be possible to find something that is more profitable then being break-even after 2 years. And if not there is always jobs elsewhere...If your husband is capable of the learning process one needs to go through to become a poker pro then he should be more then qualified to go through the learning process to do almost any job there is out there that doesn't require some bs "paperwork". Save up some money over a while and if you are in a situation where you can sustain yourself over at least 6 months without having to worry about money on a daily basis let him try again....
I honestly doubt that after 2 years he isn't capable of beating these stakes, but given the situation you are in currently it's probably impossible for him to do it right now.
Hopethathelps and good luck for the future
