Conclusion for today. I hate being born as human beings

I have similar problems. trusting others is very difficult. I am someone who never lies or cheats or steals and I live in a world of liars, cheats and thieves . being honest makes me feel vulnerable . I don't trust my girlfriend and lately we fight a lot because of this isssue. the problem is that she has lied before and she is really good at lying. every day I wonder if I should leave her and find someone who inspires me to trust her.
