<human>: This isn't quite a shock but the magnitude has definitely been ramped up. I am a 22yr old college student, SO is 21. We've been together for almost a year now. Things have been amazing, we click on a level that I've never had in a relationship. We never fight, have great conversation and share many of the same hobbies. However, the snag is her mother. 

We're from very different families. I grew up in a very rural area, southern accent and all. Went to a shitty public school and now trying to graduate from college as one of the first in my family. Her family has lived all over in a much more financially positive situation. She attended private schools, lives in a country club style gated neighborhood, the works. There are large differences in our families. 

My parents have met her and adore her. Her father seems to like me and we talk often. Her mother, on the other hand has not been as friendly. She is basically a stay at home mom with no children at home. She plays tennis and shops. Now that my SO is home for the summer, she basically unloads saying that she should date someone who is "more attractive".  Now, I'm not the best looking guy, this isn't a shock but it stings. Her daughter is beautiful and could definitely date any guy she wants. But she says she loves me and we've talked about the future and marriage has surely been on the table. I treat my SO like a queen. She is my world. However, tonight her mother went over the line. 

This is mind-blowing to me.   What am I supposed to do? I'd like to go and talk to her mother face to face (we only met in person 2-3 times)  but I don't want to do more harm than good. I'm trying to be supportive but Im in a spot where I feel like I have no control. I mainly want to know, RA, has anyone else had this kind of problem and what did you do?

Condense the text into a few key points
<bot>: SO's mother hates me. She is torn between our relationship and that with her mother. What should I be doing?
