Was my coworker just being friendly, or was he actually flirting with me?

While at work my coworker (male) was teaching me (female) and another coworker (male) a card game. I was getting confused at some of the rules which was making him chuckle a bit but he taught me it. Once I learned he said "now you'll have to go home and teach your husband". To which I replied no because I was flustered and then he repeated the no in a joking tone as he walked away. It took me a second to come up with something good to say back so I kind of yelled after him I'd have to get a husband first. Which I dunno if he heard. I'm single and have never talked about a husband nor have I ever worn a ring.
This coworker often jokes with everyone he's a pretty laid back guy. He is also a little older and way out of my league (he is your typical gorgeous player type and I am overweight). So I have a hard time thinking it could be flirting as much as I wish. I've been into him for awhile but try to stick to myself out of fear of making him uncomfortable or crossing a professional boundary. Though a couple of my friends at work know I think he is hot.

He was being friendly, with typical guy humor and all guys tend to harmless flirt a bit. But if you welcome it and advance on it. Then so does he. Then you might have work place romance starting

So, the ball is in your court.

Do you flirt back heavy and see what happens or let it go?

If he makes a joke then I will joke back with him, I'm so afraid of him realizing I am into him and him being disgusted and things getting awkward that I don't know if I could flirt I feel like I don't really even know how to flirt but if he speaks to me first I always welcome it and if he gives me eye contact I will always hold it.
