natural reaction to you already seeing someone

[GenePoole]

If you are seeing someone and it's not serious, do you tell the girl?
Would the normal reaction be to think that you are a player?
Personally, I reckon it's best not to mention it at all or say something like, I'm seeing someone but it's not going well.
Depends on the girl I guess.

This is a vague situation..

Define "seeing someone"

Around my town, the common conception of "seeing people" means you are allowed to see other people as well, meaning you wouldn't be a player

In this case, feel free not to mention it to another girl, and even start seeing her as well..

But if she isn't okay with not being exclusive, BIN HER OFF
