In itself it is not cheating. I could have a chat with a male friend that is innocent as speaking to my own mother. However, if I’m in some way trying to entice the other party or lure them in any way, I believe that I
would be considered a cheater.
A lot of chatters may argue, “I’m just flirting” but I think that even if you never meet the other person, you aren’t taking your romantic interest to the one that earned
In conclusion, if you’re goal in the convo is non flirtatious, then no… if you’re seeking romantic/sexual attention from another I would say yes.
