Married man

it’s hard to figure out if this married man is into me or not. I’ve had a crush on this coworker of mines for a while now. And now I feel like he’s into me but I don’t want it to be all in my head just because I like him. He’s well known as a married man who just had a baby. (YES I KNOW ITS WRONG) but hey you can’t help who you like. But for someone reason I feel likes he flirting. We give eachother these long stares and glares we both smile and pretend as if nobody else in the room. He give me side touches and elbow tickles, and we have good conversations. With these stares it’s breathe taking and heart stopping. We hold hands for a few when nobody is around. I think I’m falling for him. And I dislike myself for that because he’s married and has a baby. So right now he’s gone for a couple weeks from work. But came in last week to check up on what’s been going on just for a few minutes. We looked at eachother and I looked away fast. Couldn’t face him. But as he was leaving his office he came by me with a smile and say good afternoon to me. In a flirtatious way. He doesn’t act this at towards anyone else at he job or at least opens up. Is into me? should I tell him how I feel, when he comes back? so it can pass? HELP 😩
