She Flares Up Anytime She Is Called To Support Kids' School Fees, Husband Cries

The Federal government job the wife is doing was offered to her through the husband (originally meant for him), while the husband rather opted to be on the street hustling and in school too. To cushion the effect of transportation, the husband had years ago sold his Bolt business car to buy a tokunbo car for her as a means of getting to and from work.

Now the woman is working and at the same time running a side business, using the car as support.

Anytime the issue of supporting the family comes up, she flares up, whereas she sends money to family back home often (which I am not critical of). Out of the 4 kids, the husband has told her to take up partial responsibility for one of them who is in JSS 3, because the fee is high.

Is it unmanly or wrong for a husband to call a wife to show support for children's school fees (at most partial support for one out of 4 kids)?

Or is she resisting this because she is used to not supporting before now, as he has never called for her support in any way before?
