Boyfriend bad talking me

My bf is always bringing up the fact I'm on food stamps and Medicaid. I started getting food stamps when I lived on my own because I couldn't afford all my bills and to buy food for myself and my 2 kids. I still get it but since I moved in with my mother it's gone down significantly because I pay less bills then I did. He only does it when we talk about our finances because he thinks because I get help with food and medical that he's better then me because he doesn't (even though he has in the past I might add). It honestly makes me feel bad about myself. This is coming from a man who has his grandmother making most of his meals. I have a full time job and take care of both my kids financially as well as pay my taxes. I'm really just over it.
