Who is in the wrong? Bills/husband/wife

Going to be short and sweet:

Husband and wives phone bill-100$

Husbands weekly check-750$

Wife BI-weekly check-225$

Husband mad I told him I don’t want to give him $40 this week for phone bill because he absolutely can afford it and I’m saving for baby. I’m pregnant with baby #2.

Who’s wrong?

It’s metro pcs lol, super cheap phone company.
