urging to her for a relationship

i like a girl and she is 22 years old. she was my customer and so i contact with her after 2months ( when our work is done ).
we sent text to each other and she said do you like me ? i said yes! and she said i don't like to relationship with anyone because my family trust me.
we live in Iran and family is important for us. (specially for girls ).
after had conversation until 1 month without dating. she response me each nights and we text for 1 to 3 hours. i feeling she interested to me.
she talked with me about go to cinema or restaurant some times but after some minutes she changed her decision.
we had many text last day and everything was great. suddenly she block my telegram account and doesn't answer my text or calls!

i call to her with another phone number today. she answered and we talk for 10mins. she laughs and she was not angry or serious.
i know she does not hate me. please guide me because i want to be with her.

and her last text is:
Yes i know she doesn't want to be with me. but i know she doesn't hate me too! please guide me for interested her. this is her last message to me ( today ):

I'm not a kid and tell you I'm not satisfied with four messages that i tell you love me or not! whatever it's not its not different for me. I don't hide my feelings I'll just for someone that I really love him, you're always repeating the same things that really boring ( i told: give me one chance for 7days ).
