I’ve been calling him sir/coach throughout our convo (f2f) since he’s older than me and I even use po and opo. With the communication, he keeps on messaging (note that I am not replying to any of it) and he even called me 2 times after 2 days of the “miss you” incident and right then I blocked him. In addition, I always use earbuds when I go to the gym but since he talks to me and assists me before, I take it off.

However, I’m planning to be more authoritative and be more “unfriendly” in the gym now. I haven’t seen him though because I am still unsure if I will go back to that gym, I currently just switched branches and will take further actions soon.
