Is she testing my sincerity?

I thought I didn’t deserve her so I avoided her on purpose. When she reached out to me, I didn’t dare to respond because I was afraid I would fall too deeply in love with her.

My circumstances back then were less than favorable: I didn’t have a stable job and couldn’t take care of anyone else, so I decided to cut off all contact with her.

I have only been focusing on my career for the past 10 years. I have really tried my hardest. Now, I can confidently say that I am leading a comfortable life.

I saw her by chance one day and realized that even after a decade, my feelings for her are still the same. I decided to contact her and confessed the real reason behind my leaving her: being afraid I wasn’t good enough for her.

She said she was very upset, and couldn’t believe that was the real reason. I don’t know how to explain it and show her my sincerity. I am hoping that she will understand over time.

At first, her messages were dry, but recently, there have been some positive signs, but there are still times when she leaves my messages as "seen" and makes no response.

Did she finally understand my sincerity finally reach, or is she testing me to see if I’m truly genuine?

I hope you can give me advice.
