I Wonder If I Should Or Shouldn't

The title is self-explanatory, I wonder to myself if I should still believe in love even though most of my past relationships weren't that great or successful. Base upon the last guy I was with, I was hurt very badly that I had to recover from his negative self.

Like for examples, he didn't say I was ugly out loud, but his heart says it when he admires those hot models. And another thing that bothered me about him was he couldn't be with me when I am slightly suffering from hair loss, (I have short hair now) and plus he didn't like short hair girls. Because of that, I was hurt. Should I still have hope in finding Good Guys? I don't friendzone Good guys, so please don't judge me like that.
