My boyfriend told me his babymama will always come before me

Me and my boyfreind took his daughter to chipotle to get a bowl and we ran into his babymama out side chipotle , it was a long line so after while i went out and waited in the car , his babymama and daughter left, do u know he came out to the car with 1 bowl for us to share but he bought his babymama her own bowl..and he got his daughter a bowl.. I confronted him about it because i feel like why is he buying his babymama food.. He told me his babymama will always come before me .. I am hurt .. Am i wrong?
