I have to say this but as a guy who is not yet into any serious relationship,but a lady throws herself at you ,you reject it and she starts acting up and misbehaving.
she is always thinking of herself alone,always happy when with u alone and doesnt care so far she is with u alone.remember she is the one who loves u.now that the person u love or another person comes and then she starts acting possesive.acting jealous.she would be all around with the person u love so that u wont feel free to talk to the person.she justs acts wierd,immature until she totally isolates u from others and disgust u.till u shut her out? in such situation,what can u as a guy do?

As a guy...i will guy her.
