Unsure About potential partner????

long story short. Met this guy at work, He introduced himself to me first(Different departments), few weeks later his close colleague passes me his number (says he’s unable to do it himself because he was busy at the moment), We start chatting(pretty mundane talk), few days later at work he comes up to me and asks to hangout (I say yes, whenever, just let me know), he messages me a day later with a hangout date and plans, we hangout (I dress up nicely, he’s more casual), hangout was nice and fun (he mentions that he will be out of town for a few days), hangout ends, when I get home I send him a simple text thanking him for dinner and expressing how we should hangout again sometime, he replies agreeing and would let me know when he was free again, WE DON’T TEXT AGAIN!

We hung out last Monday, we worked the same day Wednesday night but I was busy and whenever I see him at work He’s usually REALLY busy so we didn’t interact that night. He let me know he was leaving that Thursday and would be back next week (this week). Im scared to make the first move and text him first. I am wondering if I should just wait until I see him in person at work or if I should break the ice and message first?

Also I forgot to Mention but he is super attractive! I was surprised he took interest in me lol I don’t think Im ugly but I wouldn’t say I’m conveniently attractive 😅 I guess Im scared he doesn’t like me after hanging out, which isn’t the end of the world but still would hurt. I don’t mean to sound vain but the few guys Ive talked to weren’t necessarily the most attractive so when things didn’t work out I didn’t feel a total loss but the fact this man is out mogging me makes me feel self conscious about the situation more 😭

I’ve never talked to a guy that wasn’t immediately straightforward with their feelings towards me, so I feel confused about this predicament Im in😀

Sorry if this all over the place and doesn’t make sense, I don’t have anyone to ask about this kind of stuff and I desperately needed to hear any sort of feedback thanks
