Selfish or not????

I want opinions my bf of almost a year stopped at the gas station he usually is buying blunts so I didn't think anything of it... mind u it's 9 o'clock and me and my three kids are in the car and none of us have eaten he goes in buy 2 burritos for himself and comes back to the car like nothing... Just the fact he didn't ask if anyone wanted something pissed me off and I bitched him out and he got really mad and said I'm pathetic and a bitch who's right??? Him or me
