Do You Trust Romantic Relationships?

At 30, at this point it's something that has been on my mind. I'm not sure I do anymore; how can you trust a woman? Or a man for that matter. When you struggle to read people, how can you trust? My experiences with women haven't exactly helped, women can be quite cruel; that's not to say men can't be, I just have no experience there.

At this point, am I just too jaded, is there a way forward on this one? I'm quite burnt out with it all. I'm really questioning, who in their right mind would do this to themselves? Why want a long term relationship?
