<human>: Condense the text into a few key points

At the outset, my girlfriend has done almost nothing short of letting me know in the past 1.5 years that I'm her number 1. She has made all the efforts in the world to make me feel comfortable around her guy-friend. 

However, her mother believes that her best-guy-friend is the right fit for her while I'm only an average person who could have done/can do better in life. She does not know I am dating her daughter and knows both me and the other guy only as persons who meet her daughter and passes such comments. 

I know this because my Gf has told me what her mother thinks of her guy-friend (very good looking, very intelligent, very mature, etc.) and me (potentially intelligent, effectively average, bla bla) exclusively, without any intentions to compare. 

The problem here is a 2-fold one: 

1. Her mother does have influence over her and the fact that influential people around her are rejecting me as her partner hurts my sentiments a little. I can deal with others telling my Girlfriend she's out of my league etc (which in fact does not happen. we both get told we're a very good fit and we feel very lucky to have each other), but her mom implying this and then also being so OKAY with the idea of her dating the other guy but not me, is not the best feeling. 

2. The fact is, he is better. He goes to a better college than I do, he looks better than I do, he dresses better than I do, is richer than I am, better read...  I could go on and on. I know I'll always meet better people in life, but this particular example combined with the social pressure is taking a toll on me and I feel defeated. And I hate feeling defeated. 

I don't know what to do. Gf understands my problem (that I'm insecure about this, haven't discussed her mom's thoughts over it) and is being patient. Don't know what to do to make things okay.
<bot>: Gf's MOM thinks her bestfriend is a better fit (who has better traits/characteristics in reality too). Hurting my ego.
