Good sign or just overthinking?

So i awhile back a met this girl in my friend group, we both liked each other but she said she wasn't ready for a relationship. We still spent a lot of time together kissing, cuddling, etc. She would mostly ask me to chill. Anyways one day she said she felt a lot of emotion for me but doesn't know if i feel the same so she just wanted to be friends. I have been chasing her ever since.

I recently thought she was flirting with me and i asked her about it and she said no, she knew i was annoyed. I stopped putting my time and energy into pursuing her and texting her. Its been 3 months and I haven’t messaged her or she hasn’t messaged me.

My friends and her were going to a concert i couldn’t make. So i had asked my buddy to get me a t shirt But he said the line was super long and no one wanted to wait in line for just my t shirt, except the girl i like. I had told my friends that it was ok and it wasn't a big deal but the girl i like waiting in this long line for me. Is this a good sign or just a whatever and why would she wait in a long line when she could of easily avoided it.

Good sign or just overthinking?
