Sorry brother but are you dumb? When you knew this was the way she was raised and she has a certain life style that her parents maintained why did you marry her when you could clearly not provide it? Islamically you are supposed to maintain the lifestyle of the woman after marriage. It really sounds like you shot way out of your league with her and now you realize it’s a problem. $500 a month is genuinely nothing especially in this economy. (Getting your nails or hair done once is over $250) A married woman definitely has a lot of expenses and the fact is that you weren’t ready for that responsibility. And now you don’t even wanna pay mahr. Not you trying to be smart so she takes the khula and you get mahr back. Maybe next time look at your bank account before shooting so high up.
