Friends?

Ahhhhh! I'm super frustrated! I have like these 2 friends, they are nice and all but we just don't click together, whereas J, T and Y the good friends I mentioned in my earlier post, we have this bond and I feel like myself around them. Let's just call these 2 friends x and y... they are fun to be with but they are just too different from me so I don't feel comfortable around them. They are kinda ego, a lil' stubborn, vain? And in a way, high maintanence. I can't help feeling pressurised. Hmmm... maybe because they have a lot of money and spoilt? Haiz, so I don't know what to do:( I just don't feel like I'm treating them like how a real friend should. I know that they treat me as a real friend and are good to me, often asking me what I want, and they understand me when I say stuff that is complicating.

x understands the random stuff I say
She is nice
She is cool
She is smart
She knows how to have fun
She is stubborn
She is ego
She can be desperate
She is insane
I love her
But at times
I can't understand her

y is thoughtful
She is kind
She is nice
She treasures her friends
She is smart
She listens
And tries to undersand
She is vain
She is spoilt
She does not understand how
Fortunate she is
She does not like people to be angry
So she uses a lot of
"chills"
She is an awesome friend
But sometimes it kinda appears as
Bribing?
Or desperate?
But I understand
That she is afraid to lose
Her friends
She is insecure.

My final question to ask myself
"Friends?"
