Polls: Flirting

I really like this guy from work. We work for different teams, so we don´t interract work-wise. I noticed from my first day at work that he is noticing me and checking me out. Back that time, I was seeing somebody, so I didn´t reciprocate. One day we were both late at work and he introduced himself in elevator. Since that day we started to say hello to each other. I can see that he blushes when he sees me and often is very nervous. Once I didn´t notice him and it looked like ignoring, so he started to ignore me and even acted offended (looking away when I tried to make an eye contact). After I initiated a small talk with him, he greets me and smiles.

This week I started to notice that he stays late at work (I always work in the evening as I prefer to arrive later to work) and even his colleagues started to mock him for that, like "What´s going on with you? You didn´t used to work that late". There are also more signs that he may like me, but he´s never texting or didn´t add me on facebook. Never initiates anything - when I smile, he smiles back, when I say hello, he does too, etc.

Do you think he´s shy or just not interested and I´m just projecting this in my head? Why would he behave this way?

ALSO ADD WHAT STYLE OF BANG YOU PREFER TO!

Thinking of getting bangs again because last time i had them i was 9 plus my hair is really boring and basic right now so just wondering what you guys think of them, byee!

I was at the exchange with my ex and his best friend and I was standing against a wall waiting for them while I'm a bit upset because I was missing my ex being my boyfriend and when we were about to get ready to leave he purposely bumps into me and acts like it was an accident which made me smile and laugh so he does it a few more times while we're walking together.. was he just trying to make me smile or does it have something to do with him probably still liking me

This guy told me he saw me at the gym the other day. And i didn't even tell him i went to the gym and i didn't tell him which one but he when he told me which gym he saw me at I was shocked! It was my gym.
Then the other day a guy at the grocery store saw me and said out loud to his friend "I think I know her name, I saw her online.". So creepy

Low-grade insults meant to undermine the self-confidence of a woman so she might be more vulnerable to your advances. The dude says something negative about your looks to try to lower your social value so he can try to swoop in there?
