Sharing Our Innermost Thoughts

I have my exams. I miss my best friend. I left her long ago. I couldn’t forgive her. I want to. But she never asked for forgiveness. Its like I value her soo much. But i feel she doesn’t put what she feels for me in words. I just know that she loves me by her actions. Is it okay to go back to her ?. She is my happiness. It’s like everytime to test if she values me Or not. I used to stop talking to her . She never asked me for any reasons. I used to not like that thing. I used to feel I am the one who is really interested this friendship
