I could see not telling her that you're loaded but at the same time I wouldn't act like I was completely broke. If anything I'd lie and say somebody bought my shyt to help out with some of the bills. That's just cause I refuse to be a user. I always said if I was a millionaire I'd still keep a regular ass apartment and lie about my job until we've been together for some time to know she's marrying me for me and not the money I got. But to mooch off of her is a whole new level of shytty.
Nah, fam, I wouldn't act destitute, but, (Real or not) too many of these stories sound women upset that she can't spend that money. If I was loaded, loaded, I'd work part time and rock only thrift store clothes and New Balances.
OP wasn't thinking about mortgage, insurance, etc. She was thinking about trips/IG, Prada, etc. Generally speaking.
Now, if she feels like he owns her money, then take that up with him and break up.
If he went so far to propose (again, she only knows because he wants to "commit"), he obviously had plans to "pay her back."
The dog thing is a bad example and I don't believe she "paid for everything" while he was just being an "aspiring writer."
My dog is 10 and I'd have to think very hard about paying thousands for surgery and this little muhfukka means a lot to my immediate family.
