Dating muslim man

Alyssa 👸💎💕 • Mommy🌻 to 2 boys 💟

I am not muslim but my boyfriend is and it is hard, is there any advice i can get.. i feel like im living my life in secret, my family knows about him and our relationship but i know nothing of his and they dont know about me. One time i kissed him and his mom was on facetime and i didnt know and she saw us kiss and asked him about it but i dont know what he said (he spoke in arabic and i only know a tiny bit) we havent spoken in 4 days because i posted a picture of us on instagram and he got mad. What should i do?
