Eating dinner alone 😞

Me and my boyfriend were having a good time and then when we got home he looked in the fridge and saw I bought a monster (first time in a year) for work and he told me I was an idiot 😞 and was like well you complain that your stomach is big but your drinking sugar how long till you start drinking alcohol. Which I don't plan on drinking alcohol ever again . But now I'm eating dinner in the kitchen and he's in the bed room eating .. he told me it's a waste of money and I could have just made coffee . And he doesn't want to hear me complaining about being big or not feeling good from it 🤯 not really sure what to do cause he's just ignoring me
