Why do guys mislead?

Do men find pleasure in misleading a girl into thinking ‘oh I like you’ then turning around and just saying to their friends “I’m just mooching her”

I really find it heartbreaking when I get lead on like that. I’ve had that happen more then once and believe me it’s not nice. I don’t know what guys think when they do that type of thing but it hurts for a long while after they finally tell you or someone close to you, “I didn’t like you, what were you thinking?”

I wonder if any guys out there have ever done this without even knowing. Or if they did this because the girl was giving him gifts for holidays and they knew that if she knew he didn’t like them that they wouldn’t get any gifts.

I’m just writing this to rant right now.. I feel heartbroken and I have this massive headache so I really need to get somethings off my right now.
