upset and annoyed

My boyfriend asked me yesterday if I wanted to go get ice cream and I told him we couldn't cause the closest ice cream shop closed already, and then he said let's get ice cream tomorrow so I said ok and we were gunna have an ice cream date and then today he comes home and starts drinking and listening to music like every single fucking day I'm with him, and he's like what do you want to do, I'm like let's go fishing! He goes nah I don't wanna, and then I was like ok then let's go get ice cream before they close since yesterday when you asked they already had closed  and he goes no I'm not fat like you, so I was like really? I'm fat? Even though you're the one who wanted to asked me if I wanted too? He also said he doesn't want to go out cause "I actually works for a living unlike you" even though I have a full time job helping my dad with his business and work at a restaurant on the side for extra cash he's said all of  this before many times. He drinks a lot (EVERY SINGLE DAY) more then just a few beers too, always puts me down, now I don't ever want to eat again... and I'm getting tired of him saying I don't work, I work with my dad with his business and always tells me "I don't work with my daddy for money unlike you" it's because my dad wants me to take over his company. Funny thing is my boyfriend has the same job as my dad BECAUSE my dad got him into it! Really getting sick of being treated like this but I love him too much because when he's nice I always forgive him. We've been together 5 years this December.
