Ladies, help please.

Kylie
I absolutely love my SO, we are best friends and have such a good time together - but we've both been done wrong in the past, so our trust is a little messed up! I know he wouldn't see another girl or disrespect me, I can't help but to worry and be the crazy girlfriend sometimes that's too protective. I need some advice on how to feel more confident about myself and my relationship! Please help.
