Why do some girls hide that they're seeing other guys?

Anonymous
I went out with this chick 5 times. I asked her at the start if she's seeing anyone and she denied it. After 2 outings, I asked her on a proper date. She said she just wanted to be friends and isn't looking for anyone right now. So we went out as friends another 3 times. I found out from a mutual acquaintance that she was sleeping with another guy all this time (4 months) and they recently broke up. I broke off my friendship with this girl, as I hate liars.
Same story with 3 other girls.

Why do they do this? Why not just be honest? If they want to be friends with a guy, why is it wrong for them to just say they're seeing someone?

It's frustrating and a waste of time, and makes me despise the girl in the end.
