He's into me but not totally ready yet

Kamden
So I posted this story a couple days ago but now I'm just trying to get a feel for how to act around this guy. We both like each other we have a mutual best friend, and he tells my bestie that I'm cool as hell and he really likes being around me and that I'm really pretty. So anyways, i know I don't need a relationship right now as I'm currently going through a divorce. But I just don't know how to act around him. I feel like I constantly have to check what I say before I text him or something because were both not ready and I really don't want to make things uncomfortable. Now mind you this I'm not excluding dating other men or anything but the thought of him flirting with someone at a bar just makes me cringe. He's not the real flirty type of guy but just the thought of a girl coming up to him makes me madder than hell. I just hate this. I haven't dated in over 3 years (I was with my husband) so I don't know how to act now!! I know we aren't in a relationship but how do I keep my cool? Ugh. I've already decided when he goes on a trip with one of my best guy friends next weekend I'm gonna leave him alone and not text him because i don't wanna ruin his time and I definitely don't wanna be too clingy right off the bat especially when we aren't even dating. Guys I really just hate dating Hahahaha. Please help! And thanks if you read all the way to the end!!
