Do males want to keep in touch with a girl they only see as a friend? (context)?

I know when it comes to this it is not a good idea to generalize. But I was wondering. I had a coworker who was really polite with me, and with everyone in general. Really. A really carefree, talkative and easygoing personality. Apart from that, he has a girlfriend. He has been in a relationship for 6 years. Apart from really quick conversations at work, or very few messages we exchanged due to work, it is not like we are GREAT friends. Not even friends. He is just really nice and likeable. When he saw me, he would greet me and call me hey little girl! (I am physically too petite and skinny). But he is like that with everyone I guess. I am not working there anymore. We were teachers at a school. I was fired and some coworkers asked me what happened. He (the guy I am talking about now) asked me some hours ago what happened. I explained and we exchanged some conversation. Then I kind of greeted him like some type of farewell, wishing him luck to him and everyone and told him it was great to have him as my coworker. It was kind of I wanted to cut off the conversation as I did with everyone to delete his number. I did that with all of my coworkers because I didn't see the point in clinging onto people I am never going to see again. He wished me good luck in return and said "I hope you dont get offended if I reply to your cat stories". And I started to overthink that he somehow didn't want to not talk to me ever again and said that like "don't delete me". Why would I get offended if he replied to my cat stories? I also wonder if there are guys this nice who want to keep in touch with people they are not going to see again. I dont know, usually people and guys in particular don't do this.
What do you think?
I am overthinking because I always found him interesting but I know he has a girlfriend and he is not interested in me in the least. I dont think I am even his type, considering his girlfriend is physically different from me. Therefore, his taste in women is not me.
