Search Results: being friends again

So context: We used to sit next to each other in business class and we were very friendly he was super flirtatious - playfighting, teasing longing stares, lovey dovey comments.

. I mean this one time I was lowkey annoyed at him and moved to the far end of my chair and he pullec me closer to him- problem he had a girlfriend granted things were weird between them but I felt like it was wrong. He ended up breaking up with his girlfriend and here's me thinking he'll confess to me, wrong he got with his ex girlfriend's best friend. I was annoyed and made a comment and we drifted apart as we moved classes etc etc. he definitely knew I liked him 100%.

Here's the issue: (~5 years later present day) I have him on instagram and he always watches my story first, well I wanted to talk to him so l accidentally sent a reel to talk and it was so easy and free flowing with that teasing we had before- he even suggested we meet. I like him ano maybe I'm just reminiscing my young teenage crush and he's the one I feel got away, anyways I want to text him again it's been a week but I want him to chase me to want me to text me.

So do I text him, or am I moving with a lack of self respect with the past being like that, any help is greatly appreciated.

He was nice to me. He would cover me for breaks without asking when we first met. He initiated every conversation but didn't initiate conversations with me as much as he did with other people. blushes and smiles, with eye contact when talking (but he blushes around everyone) he told me twice that he missed me when i missed work. Avoided looking at me when around each other sometimes, but then would stare at me and smile at me other times. Tried to touch my hand when grabbing the same thing, i think. I felt like there was tension when we were around each other. He was a flirt, but he flirted with everyone. Would text me first and ask to play video games together (online) offered to hug me as an apology (over text) when i mentioned he did something that was rude. At one point, he was super dry over text, but then he started being more effort when texting soon before he quit, making me thing he wanted a friendship outside of work. Called me his friend. When i would talk to him with his friend around, his friend would smirk at us.
Then, It was his last day of work. I didn't want to make him feel bad, so when i was saying bye, i had nothing to say. he said i looked happy, but i told him i wasn't. He offered me his work shirts, and then before i could respond, he drove away really fast. I texted him and told him i would miss him, and i enjoyed working together and to text me anytime. He said that was sweet and "you too" then he started being REALLY dry over text and taking like 3+ hours to send a one word response. I thought he was just busy, but i got a weird vibe. I ignored that feeling until he decided to stop by where we work, and he waited until i got off to stop by. I texted him about it, and he was dry again. The next day, his friend was VERY standoffish around me. My friend told him i missed him and he said he didn't believe her, and then said "that's nice" Did i do something wrong? So confused
