TITLE: Mother in-law issues
POST: Pardon the format as I am on mobile. 

To begin, she's not technically my mother in law because my boyfriend and I are not married. 
I simply adore this family, I love all of them to death but it seems like I could be replaced tomorrow and no one would really be bothered. This bugs me, how have we been together this long and his parents (specifically mother) be indifferent about me. I see the way my friends interact with their "mother in-laws" and it is so different than the dynamic we have. Even my best friend notices when she is around that she's not very enthusiastic about me. 

For what it's worth she is an Aquarius.
TL;DR: 
my "mother in-law" seems standoffish with me and I don't know how to win her over!
