Capricorn man in love with his capricorn classmate

She is so cold. Very selective in choosing of friends. Finally got her number after graduated for sometime.
Had a girl friend at that time.. And broke out soon after I got this cap girl number. I started to text her and said I need someone to talk to. She actually came out and have coffee with me and let me confide. Soon after that day, I did occasionally msg her to talk or to ask out for coffee or lunch. Sometimes she will agree sometimes she will not. Ok this is nothing. The problem starts here, she do not like to reply. And our conversation usually stops half way. Even if I asked question. And so one day I jokingly texted her and said I know what is her hobby and she replied me. So I said to her your hobby is to ignore me right? She said no and that's her usual problem and I'm not the first person who told her. After that we met out and she explained to me again. But, this problem stil occurs always. But there was oce she actually take the initiative to ask me out for coffee. And this is the first time. But still, the texting thing, she just dont like to reply.

She is a very workaholic capricorn which very the same as me. What can I actually do to get her attention?? Please help!
I jus wanna try hang out like a friend. I did not advance or make known that I'm interested in her.

What can I do?

Yes, call her. I hate texting exists.

Thank u all! Sometimes I did straight away tried to ask her out. But sometimes u know I just wanna text with her and chat abit as she is always busy to meet up. How do I start a conversation ?? Or shall I jus wait?? I don't wan to confess. I just wanna hang out more like a friend.
