The guy is manipulative, gets involved with her and even kisses her, just to then leave her and say he doesn't want a relationship. You pretty much got yourself involved with her, made her rely on you and even gave her the feeling that there could form a relationship, just so you can leave her then? At least they got together, but it doesn't seem that he planned on getting together after telling her that he doesn't want a relationship, which makes it really shitty as he gave her so much hope and even kisses her. He pretty much played with her feelings.
And then his great idea of forcing himself on her? That's a no thank you.
And the girl is so meek too.
