boyfriends mom

So I've been dating my boyfriend for about 13 months and I'm absolutely in love with him. Every since the beginning of the relationship his mom has always had her restrictions on when he could see me and when we could hangout. (We're 16 and he has his lisense). I myself am not a very good socializer I have anxiety and get stressed out and don't know what to say or talk about so I'm usually just sitting there awkwardly listening to people and occasionally nodding. Recently I asked him what his mom thought about me because honestly I feel like she hates me and she always says she wishes I was like the other girls he brought home. I don't know what to do.  She has said some really hostile things and I don't know how to handle this. I usually don't care if people don't like me but she's important and I try and it never works. Any help would be Greatly appreciated.
