Pregnant hungry & broke

Relationship is going completely downhill an im really cool with it. I mean why would I care about fixing a relationship with a guy who doesn't care if I eat or not. For goodness sake im pregnant with your child. How can a guy live in the same house hold with his pregnant girl an not bother to offer me ANY food or money to get food? I was out of work for a month an half due to moderate hypremesis gravidrum (severe form of morning sickness) so of course ive missed some paychecks, now im back working an it still takes a few weeks to actually get a check cause ive been out so long, yet he still doesn't muster the words of food, but he buys him $7 burgers arbys an so much more. Im going into my 2nd trimester an my appetite has picked up tremendously. I wish he'd understand this is not healthy for the baby not just me.
