Is he interested or just being friendly?

I have been talking to this guy at the gym for several months now and we just talk about random things. I hurt my arm months ago and he would say I don’t want to look all cute on the beach wearing a brace and comment on how tiny I am. But recently we still talk but not as much.
The other day he said my hair looks like and he pays attention to detail I told him I’m going out to lunch with a friend. The next day he asked how the lunch went and told me bars he goes to and said I should go but never actually asked me to go with him. But here’s the thing he told me months ago he’s getting a divorce and that he and his wife are separated but will still say his wife so that’s confusing. Then I see him today and he didn’t come to and talk to me so I’m just confused. He’s giving me mixed signals I feel.

Is he interested or just being friendly?
