in love with an armenian girl ?

[Daniel]

Hi, I am a 14 years old egyptian boy living in Egypt .in November 2011 I met an armenian angel who changed my entire life, her name is M . One day I found out that she is 5 years younger than me and she is armenian . I kept seeing M few times per year for the next couple of years, but constantly knowing her news from her
brother from secretly checking her mother's
Facebook profile . In 2014 I sent a friend
request to her father and mother, her father
didn't accept my friend request but luckily
her mother did and finally I sent her a
request and she accepted it! We talked few about 10 times and most of the times her
brother would interfere and say stupid
things like : go study punk! , leave my sister
alone she's just a kid! Now it's been a week
and she didn't talk to me and didn't reply to
my messages(the messages were seen)
neither liked the photos of her that I
tagged her in.
And there's another prob her family is richer than mine.
What should I do
