Is it okay to make a purchase without hubby’s knowledge?

He’s at work and won’t be home for awhile but there’s a sale I really want to buy something from.

I’d spend $45 dollars, never in our marriage have I ordered makeup without telling him, if I do it it’ll be the first, he’d def say no…

I bring in a small amount of money, only $145 a month. The account is a joint account.

My mom was a victim of financial abuse, so maybe I took some of those values with me. I just don’t want him to feel like I’ll regularly spend money behind his back.
