Drowning in debt... time to end the relationship or try harder?

Is this too small of a thing to consider ending the relationship?

I love my boyfriend, but we’re both in our mid twenties and I’m getting too old to be living under someone else’s roof. We live in his uncles basement, and I want to move out within the next year.

We make enough, but the money isn’t being spent wisely. I make about $2200 a month and he makes $1700 a month. Rent around here is at most, $900. We could get a place for $600 if we really look. However, he’s not ready to move out. He says he is, but then he’ll freak out about finances.

He has gotten himself into almost $20k of debt. I paid all my credit cards off in the last year, and have started saving, yet whenever he gets paid he wants to go out and blow it. For example, he got paid and wanted to go buy the switch to play animal crossing. I managed to talk him out of it, but I feel like if it weren’t for me being the voice on his shoulder then he’d continue blowing his money.

He’s not making any efforts into paying off his debts, he says he’s too overwhelmed to begin, then I remind him if he doesn’t start it’ll never get paid off. He gets so stressed out when he looks at his statements and will make plans to save and not spend so much but he never follows through. It’s frustrating to watch him self sabotage himself.

I’m debt free besides my car, but he has the $20k on his credit card, his car, a wreck he’s still paying for, and $600 to pay off on another credit card he had to open to get new tires.... and I feel like it’s a little far fetched to end things just because he spends his money too easily, but then again I know that’s one of the most common things couples argue about. What should I do? I feel like it’s not my place to really talk to him about debt because we’re just dating and not married, but at the same time I’m just trying to help.

It’s gotten to the point where I think maybe I should just move out on my own, but I feel like it’s wasteful because I know he’ll want me to come to his place since that’s what he’s used to me doing.
