Trying to Keep this short
1. I liked this girl (not romantically).
2. Our awkward relationship strained when I asked for her number she never gave and apologised for giving her the creeps.
3. To make things worse I wanted to make it up to her, so I sent her a wallet that I know she was looking for online, I found a very cheap deal so I sent to her anonymously.
5. I didn't have any track on the item, so I had to ask her. She was surprised and asked why I sent it and I really didn’t have to do this. I went apologetic again, and told I just wanted to give her she can use, I sent it anonymously (?) because I didn't want her to feel that I am trying to buy her attention and make her feel obligated. So I requested her to block me out from her account.
6. She was surprised why I would ask that? and she liked the gift, she just never assumed I would send her anything.
7. We stopped talking after that, we can still see each other on social media. She stopped liking my posts except for the ones that are related to love and life.
8. Now whenever we bump into each in person in real life, we still say hi to each other, and she posts really sad or motivational things on her social media, just after a few hours.

Are those meant for me? Should I care? Am I over thinking?
