Yes

yeah! someone's appearance has nothing to do with who they are as a person. they just won a genetic lottery and that's it, whether I trust them or not comes from their personality

Trust them with what? It always depends upon the person. One person may keep my secrets, but not pay back $20 they borrowed. Another friend will pay back the borrowed $20 but can't keep a secret

The truth is that I am very naive if I came to think that my ex loved me, why not?

Let’s be real. Your opinion on looks is really up to your personal standards. My “pretty” might be different from yours. How you feel is really dependent on you, not him/her. How you relate “trust” with another individual is solely based only on your own personal experiences and not the other person. Your “trust” has NOTHING to do with him/her.

Yes, why not?

I don’t think being pretty is a reason to trust or not trust someone.. 😘 like idk how that would even matter one person might be super untrustworthy and the next the most.

Uh, yes?
There is no correlation to look and loyalty.
If a person is a shit person, it doesn't matter what they look like, you'll find out eventually.

What does someone physical appearance have to do with anything with being trustworthy? Lol

Uh yeah? The two don't relate.
