Christian ladies

So ladies on here that are very Christian.. I’m 19 and I’m dating somebody who doesn’t celebrate holidays, i don’t necessarily know what religion he is i believe he told me that he believed in many gods, and that’s kind of a bummer, mom is disappointed bc we are very big on religion she wants me to cut him off but idkkkkk bc i love god and i do wanna marry someone who loves him too. What y’all think .. i think he said he would come to church with me but i don’t believe he will change bc u change people please help Idek .
