In my observations, if there are financial difficulties in the family, the relationship between the spouses deteriorates and most often the wives blame the men for not being able to provide for their family. Conversations about equality quickly fall silent when it comes to earning money, because women often earn less and this is clearly not enough to provide for the family. If there is a gambling addiction, then this will only complicate everything, but this can also be dealt with, the main thing is that there is a desire for this on both sides.
Oh man, I would be grateful if my partner willing to share household expenditure even though she earn less. It's not about how much she can give, but it's about the mindset both of them working together to pay bills.
Imagine if you live in a country where the man must provide EVERYTHING e.g. household (yourself, your partner and your baby), your partner's desire, your parent and your parent in law.
Even your partner is working and get paid higher than you, she will treat every penny she received is for her alone.
