Flirting

Okay so I used to like this guy and we talked like all the time like we literally talked until 2 or 3 in the morning a lot during the summer and theeeen I scared him off cuz I was figuring myself out and being in a relationship scares me for various reasons like having to open up and stuff. That's besides the point. Anyways, I like him again and I want to be able to kindof flirt without flirting. I told him we need to hang and he was pretty excited about saying yes but I don't know what to do or how to flirt and need help...
