Well... that's women nowadays they either cheat on you because the other have a bigger dick or richer or more attractive.
I have trust issues too believe me.
You're perfect the way you are those sluts just don't understand you.
Society is fuck up and their brains automatically set up a standard either your 6ft+ and make six figures and last long in bed or you're nothing.
I'm yapping again lol.
If they cheated it's their choice not yours. It's not your fault.
I'm here for you bro
