Should I forget about him?

there's a guy who’s around my age who works a different shift than me so I never really get to see him. We happened to work the same shift once and he introduced himself. His name is Michael.
A male colleague of ours threw a party yesterday and Michael wasn’t there. One of my female friends at work is close to him and is trying to set me up with Michael. He’s not my usual physical type but I find him cute and nice and sweet and everyone says he’s a great guy.
The other day Michael came by our job after the standard work party which I couldn’t go to because I was at work to talk to a couple of his friends.
While there I didn’t think he was going to talk to me but then he came out of a nearby room and was like “hey Stacy I didn’t see you there. How’s your night going?” And small talked with me and then started another small talk convo with me while there. He eventually was like “well I’ve overstayed my welcome” and smiled and motioned bye and I smiled and waved bye also.
The next day I was scrolling through LinkedIn when I got a notification that he viewed my LinkedIn profile. This was about a week ago. The party was the other day and he wasn’t there. I asked the guy who hosted the party if Michael was going to be there and he said he told he was and tried texting / calling him but he didn’t answer. Michael didn’t know if I was at the party or not because we didn’t talk about it.
I was upset because I was going to use the party as an opportunity to finally talk to Michael more. I accidentally viewed his LinkedIn profile too at the party while showing a friend so he probably got that notification lol but I’m not sure.
A few nights ago at my friends house I decided to add him as a connection on LinkedIn.
It’s the next night and he hasn’t added me back yet. I’m regretting doing it lol. I figured because he viewed my profile first. Should I forget about him? Or give it more time? What do you think happened?
