Does my married coworker have feelings for me?

Anonymous
We work as a two person team basically where I work. So we spend a lot of time together. But he has seemed at times to act hot and cold almost like a switch is flipped. He’ll be incredibly warm and friendly, even flirty, at times, and then the next like he couldn’t care if I fell off of a bridge. Please take note, I do think he is friendly by nature and a bit flirty in personality.
However it seems he flirted more with me than the other females (however we do spend the most time together). He would always sit next to me at lunch, except for once or twice when he’d oddly make a point to sit somewhere else. ?
Once I mentioned to him that I had met and talked to another male coworker and he quickly was like, “when? When did you talk to him?” It was odd and I could have sworn he almost sounded jealous? He’s confessed some frustrations to me about his marriage, where to word divorce was even mentioned.
Now recently he found out that my marriage is ending. He immediately wanted to call me and talk. He spent the very very long phone call making sure I was ok, and asking me and going over with me things (almost like a protective dad or brother).
His sister (who he is very close to) has also gone through divorce similar to me. So partly I suspect perhaps he is projecting his sister onto me and acting more as a concerned brother.
At work I’ve often noticed him noticing me. My legs etc. And last night during our conversation he even suggested we go snowboarding together next winter up in the mountains. Which I know he does alone, and then sleeps at a house he has up there.
Please reserve your judgments. I am in no way saying that I intend to have an affair with a married man. I just need help interpreting his behavior.
