I've had my share of orbiters back when I was younger and was on the internet 95% of my day. Especially being in the gaming community as a female, it's very easy to pick up orbiters.
I, like others, made the mistake of feeling like it was 'too mean' to just be straight up with them. My only advice is to be very direct with them… something like, "I don't want any confusions between us, so I just want you to know that I'm only interested in a friendship right now."
You'd be surprised how many men will choose to cut you from their life right then and there! (good riddance)
Honestly, If I had this mindset/advice when I was younger, I would've avoided so much drama and headaches. Just think of it this way, if you
were interested in someone else, wouldn't you want that person to be honest with you if they didn't have any feelings for you back?
Another important note though, men are not completely innocent in this situation either. Men need to stop treating every woman that they come across as a potential girlfriend instead of just a regular person on the internet/in game/job/etc.
