Am I overthinking or not about this guy who is married at work ?

Usually always nice to me like will always say good morning to me first, always asks me for gum, notice him watching me here and there, asked me one morning if I was going to get a doughnut that someone brought he came up said good morning we had our little small chat than asked you not going to get a doughnut for yourself? Than every time I be talking to my friend in another language he will try copying by interrupting us and like the other day I was walking out and some how he caught up with me and start asking me where I’m going for lunch and he keeps telling his friend to pass on to me that he said “hi” when he really can just pass by and say hi if he wanted too so am I overthinking everything or he just messing like I don't know
