Why would a guy flirt if he isn't ready for a relationship?

Why would a man flirt with a girl, tease her, smile and laugh, call her darls and darling and act interested. But he says he really likes the girl but isn't ready emotionally or in the head for a relationship yet due to every past girlfriend hurting him and ripping his guts out, and says he can only offer friendship right now?!?

Also if the girl tells him she's willing to wait around for a bit and just be friends until he feels ready but asks him to tell her if he doesn't see a future with her down the line and not to let her wait around for no reason why doesn't he answer?

Just to add that he's a genuinely nice honest guy an not a player, and has really been hurt badly by his ex wife and girlfriends since clearly leaving him having trust issues and being guarded with his heart

He stopped texting and calling, but still flirt in person and get jealous if I mention another guy. It's been 4 months of him not calling or texting but flirting when I see him and his best friend has started talking to me and being nice.

Just recently he has started becoming more shy around me and calling me darls and darling everytime I see him. I stopped contacting him to give him the space he wanted, but text him last wk and he actually replied, when for the past he would just ignore my texts
