Search Results: changed since college

Me and my "best" friend let's just call her jane.
Jane and I have been through a lot together. We have survived high school for 2 years together. But then college separates us but we would still call and text each other frequently updating each other about our lives, new friends, family and more. Even when we are upset of each other, we would talk it out smoothly and everything will get back to normal.
I love her. a lot.
There was a time when I loved her more than a friend but i confessed to her and she was absolutely accepting. She even helped me move on. I told her that nothing will change between us even if i move on because i still love her as my best friend.
Now that i have moved on, she seems to be distant. I don't know if it's just my feeling or if i seem to be acting differently to when i had feelings for her. At first, she'd always tell me that she's busy and i'd be fine with it since i'm busy too with college.
However, she's actually really supportive of me and my crush being together. There was even a time when she's not mentally alright and i tried so hard being there for her. But when she's back on her track, she is distant again.
After 2 months being distant and i feel like our relationship is one sided from time to time (and me not doing anything) i asked her if she wants to call during the weekend. She agreed but when i asked her what time, she didn't answer and gave me a silent treatment. When i see my followings on instagram, she have liked posts and even changing her ig profile picture but she has not yet replied to my dm.
What do you think i should do?
