My issue

I often think that if someone compliments me, they are trying to manipulate me. I want everything forever. My brother says, "Men and women can't be friends", so I never had male friends. It's not immaturity, it wants to protect me. Like a person, I want him for the rest of my life....thinking like this is wrong?. However, now people easily break up with each other, and overthinking is not wrong. Overthinking is something that provides a solution to every answer. But now people say being emotional is like being a fool. How can I deal with trust issues? How can I trust men? How can I stop overthinking? Idk how to deal with this
