How are woman so unsympathetic that they will take advantage of a person’s heart for there own gain?

Man I feel like I really know how to pick um. Picking some of the worst girls to fall with has gotta be a sport in the Olympics and I’m right up there either way the best of the best. And you know what I think it’s my nativity more then anything I just don’t understand I never have since I was young I could never understand how someone could use or hurt someone that’s done nothing to wrong them just because it benefitted them. In fact I’d say nowadays in some cases you’d be looked at as stupid for not doing just that. But more than anything in dating this always cuts me deep when ya find out what kind of person someone you like really is behind the nice gestures and kind words. And it’s just nothing I don't know if how to feel I feel a mixture of great anger and frustration so much so that I wanna put my fist through a wall. But also great sadness and pity, I have an empathetic heart at my core it’s turned pessimistic over the last few years almost cold and a lot of the time I seriously wish it would freeze over. But I just can’t there’s always a little bit of hope in there I feel like that’s the childlike part of me just hanging on to my humanity. Anyway sorry for the rant kinda feel like I went off topic but hopefully it all ties together.
