Man And His Family Speak Another LANGUAGE In Front Of Me

Leo and Rebecca in The Morning BUZZ QUESTION...Hey guys not sure how to handle this...Newly married...My man and his mom and sisters, speak another language in front of me. It didn't bother me at first but they do it all the time now. I feel like they are talking about me and I asked him about it and he said NO they don't do that. I just feel out of the conversation all the time they come over or we are around them. Any suggestions???
