Help me with this guy

So I started this job about 1 and half ago me and this guy always flirts with me I do the same and we try to find away to talk to each other the other day he was playing around and said scary movies really turn me on and this girl I work with said to him if your really trying to impress her don’t say that and me being slow and not understanding till now she was talking about me smh. Today I was on tinder and found him so I swapped right that means you like them or whatever 1 hour later he did the same and we matched. I’m thinking I should go for it but at the same time I’m wrong about people liking me 99% of the time what should I do 😳🙄🤔 and I work tomorrow and I think he does to should I say something leave it as it is so many questions idk
