Guy's Behavior

Does he just cares? Is it just attraction, some kind of lust, than anything more? What does his behaviour mean?

We have history. We just like having fun with each other. Even when he was in a relationship he wanted to have fun but I didn't and I made that clear, that I won't ever cheat with him.

Then his girlfriend broke up with him, he wanted to reconnect, but I just wanted to have fun and broke things off. He kept getting back to me and said he cares. I made clear all the time that we can't be a thing.
But yeah there were times that I got back to him multiple times and he know that we both have some attraction to each other.

So we kept it at having fun. I send him videos but he never ever had shown them to others.
Lately he has some videos of me without my head on his mobile screen saver, few vids as gifs. He showed it to me and he acted as if he was really proud to have it on his mobile. It was good to see that no one could recognise me and it were only my chest area. So I don't mind at all.

I said he could better find someone else.. so yeah he dates also others.
Yet he has the videos of me still as his screen saver.
I think it's because he likes my boobs a lot haha.
That's why I also can't start something with him, I think.

It's also I think he just can't be single. I don't know, I'm attracted to him but I just doubts what he is after.
