What should i do when a guy says he's uncomfortable with me?

This guy..I cant get his nature. He used to flirt with me , talk a lot of ual stuff and would say thats platonic friendship. I felt weird so I hinted at no talk , as I did that the guy stopped being very friendly...and started behaving as though I was running after him when I would just send him msgs. He would nevertheless ask me to meet him, but since I couldnt trust him I dint. Then r conversations reduced even more , I thgt perhaps I had hurt him. So I asked him to meet me and he said he was uncomfortable with me because I was coming to him too much , I was overly possessive about him , msged him too much, and that he got put off by immature women . I find it weird. And this guy send unlimited friend requests to lot of women and has treated women this way for a long time..im guessing...from his past scraps n stuff...did a little snooping. But he says he's not a casanova , but a machine or that he loses track of his pants. Is this guy mad ? and he's saying he's uncomfortable with me ! anyways i dunno whose fault this is. We dont talk anymore. what should i do ?
