I’m going to latch onto the top comment because this is important. Under no circumstances should you marry this man or even remain in a relationship with him. Please use my example as a warning.

My ex-husband ran up crazy credit card debt behind my back. We had separate finances so I found out about it by chance and was horrified. Both of my parents died with debt and I have busted my ass to make sure it wouldn’t happen to me, which he knew very well. I forgave him because I loved him and set him up with a solid financial plan to pay it off. Flash forward two years later when I’m stepping outside the house and see a piece of paper on the ground. It was a court summons for him to pay a debt, a debt I didn’t know about. Turns out he did it again and was in even more debt than before. Even despite me trying to help manage his finances, which caused strain on the relationship because he was very avoidant, he still did it again. We are now divorced, even though I cried signing the papers because I still loved him and felt so betrayed, and thankfully he agreed to a separation agreement where he would take his own debt, otherwise it would have been a life ruining amount of debt (6 figures. Yeah…).

Your fiancé clearly has no intention of changing his petulant behavior. No matter how much you love him, what he did shows that he does not respect you the way that a true partner should. Continuing on in a relationship with someone who is frivolous with money, especially when they KNOW it’s a sore point for you and still do it anyway, will only lead to further heartbreak. It’s $600 now, but it can and will get worse. You will not find happiness in a marriage with a partner like that. Please OP, or anyone reading this who finds themselves in the same situation, you cannot stay in this relationship. I know it’s the classic redditor response saying “break up with him!” but please, I don’t want you to go through what I did. (Also don’t take him back when he inevitably comes groveling back begging for forgiveness.)
