I would sit down with him, show him the numbers, and get his input on the plan. For some people, that’s all they need and then they’re onboard. But unfortunately for some people, it takes months of seeing their partner succeed while they continue to drown before they got onboard. With my husband, he was resistant when I first mentioned budgeting because he thought it meant we couldn’t have fun or buy things on a whim so we went 7 months living paycheck to paycheck when we earned more than enough to not be living like that. We were constantly eating out due to poor meal planning and grocery shopping and just barely paying down debt. Finally one day when we were out at dinner my husband said, “I’m tired of not having money. ” I took that as an opportunity to bring up cash envelopes again and he again brought up his concerns and I told him we can still have fun and buy things for ourselves, it’s just planned for now. Within the month we found ourselves being able to throw $1500 to debt and it slowly went up to maxing out our snowball at $2200. Since then he’s been grateful for my budgeting and our cash envelopes. We’re not perfect by any means but by working together, we can still make it through off weeks (like how 2 weeks ago we went out to eat like 3-4 times instead of once a week )
