My partner doesn't care about having a joint account

My partner doesn’t care about having a joint account with me.

It’s because I have a bit of a spending problem… When I see both of our paychecks together & how much cash all of us have, I can’t help but to splurge a little; Okay, okay, maybe not a little.

Anyways, our partner is seemingly getting more aggravated by the amount of cash I am spending each month on things that are not dire. She seems to believe it would be better to save up for a holiday or for an emergency fund. She also mentions wanting to start our kid’s college funds. All of that stuff is important too, although I believe a lot of that can wait, besides, I don’t buy stuff that often, usually only once a week. I suppose I crossed the line though with our last purchase though, because now our partner is giving me the silent treatment. Why? Well I will already admit that I spent more than I usually do, although I believe it is worth it! Anyways, I had a stranger stop me on the street & she was holding a sign that directed to her Heating & Air Conditioning store! She recommended I go & take a look in there. I wasn’t originally going to, even though she provided a discount for anything I saw, so I had to look. I ended up walking out with a portable air conditioner & a smart control unit, however my partner was not cheerful to say the least. She questioned why all of us even needed a portable a/c when ours work just fine, & well I didn’t really have an answer for that. I purchased the smart control component because it looks cool, & she didn’t care about that answer either. Oh well, I suppose I’ll keep the Heating & Air Conditioning component in our room if she doesn’t want to use it.
