How to make my mom meet my boyfriend?...she refuses to accept him?

long story i just want my mom to meet my boyfriend (been dating 2 years!!) she refuses to accept him still and say bad stuff bout him and she never personally sat down with him so what can i do. should i do the unthinkable and invite him over my house like any friend she know who he is, but i doubt she has the guts to kick him out. or should we go diner or cafe i dont know what to do. im 20 and he is 24 , and 2 years of dating secretly....i had enough of lieing cuz of my mom
