Not sure what to feel :/

So for quite a while I've been crushing on this girl, say about 4-5 months now. I don't know her personally but my friend dates her sister and i know a lot about her through him. She is the perfect mirror of me in terms of hobbies and interests. so yeah. anyway i thought i should overcome my cowardice attribute and message her, (as I live in saudi arabia you cant directly approach a girl as you can get into deep problems). the first time i messaged her was about 2 months ago, she didnt bother replying for 3 days and she screenshot my message and sent it to her sister. which is how i found out from my friend. so i tried to forget about her since she didnt seem interested, but i do know she, as a person has a very good kind heart. recently i watched an anime and i felt quite emotional and felt as though i needed a girlfriend (dont ask :P) so i tried messaging her again about 6 hours ago saying hi and that she seemed like a nice person, so i thought it would be right to say hi again yada yada yada. in case you were wondering the first time i just said hi and nothing else. so thats my story and yeah, if you could help me discover what im feeling or what im supposed to feel then i would really appreciate that :) im really nervous as to what she will reply with :( :upset:
