Husband Spend Extra Income on Zaza

Need other people’s POV on this..

I earn more than my husband, so I cover about 60–65% of our expenses to ease his financial burden and give him space to still enjoy his income. I don’t want to keep score because he’s generous in other ways.

Recently, he was able to make extra income, but instead of contributing more to the household, he chose to spend on zaza vapes. The first couple of ones, it was okay, he kept saying each one would be the last. But he ended up buying 4-5 times spending about $180-200.

This has happened before, and we’ve already fought about it. I’m disappointed that it’s happening again. I don’t mind him using zaza occasionally.. I think what hurts me more is that he isn’t able to keep his word, and as his wife, ofc I want to be able to trust his word.

I also think he’s being financially irresponsible, and it frustrates me that he doesnt seem to make it a priority to contribute more to our shared expenses especially when I’m already carrying more of the financial load for both of us. I feel disrespected, taken forgranted, and (a bit dramatic but…) left out to suffer..

Am I being too hard on him? How

tl;dr - Am I being hard on my husband for spending too much on non-essentials given that Im taking on majority of our financial responsibilities?
