Is my coworker being nosey or trying to get to know me?

One of My male coworkers and i rarely work together. Since I’ve been with the company we’ve worked together once and we barely talked i gave him a little info about myself and we haven’t worked together since. Last night we worked together and he asked did i have a man and what were my weekend plans …. He also asked me three different times through our our shift was i still messing with my ex. He also asked why i was single. He made a joke saying he had big hands to hold big things (i am a bigger plus size girl)

Was he harmlessly flirting or just trying to make time pass since we had to work together for that day
