Hello steyor and welcome to a2k
So let's do the math, you're paying $ 804 in mortgage + HOA fees
utilities, cable etc. are probably another $ 200 per month, adding it up
to $ 1004. His share of that would be $ 502.
Who pays for food? For a family of 4 (I include his kids here) you
probably spend another $ 800 a month for food an related items. His
share of that would be $ 400, adding his fair share up to $ 902/month.
Does he share household chores with you, like cooking, cleaning, laundry?
Your boyfriend earns more than double your salary and he thinks that
paying $ 600 a month for living expenses and housing is more than he's
willing to pay, then you got a cheapskate and a freeloader on your hands.
