Why my boyfriend really likes to leave me in his mom place?

My boyfriend and I are in a long distance relationship, usually he is the one who comes to my country. But last month i went to his country for a month, i stayed in his place. But he sent me to his mom’s place often. Even though his mom Is very nice, but I don’t speak a single word their language. So it was always awkward, because we need google translator to speak to each other.

Does it mean he doesn’t like me? Want to keep me away from him?
