It isn't guys you need to learn to trust - it's your own judgment.
Just because a guy screwed you over doesn't mean all men will behave the same way. So you need to accept that your past relationship was a unique experience that has no bearing on future relationships. Each guy deserves to start with a clean slate or you will be stirring up all kinds of problems that could have been avoided.
So - you need to allow yourself to heal from your last relationship. You need to accept that your ex is responsible for his behavior; his betrayal is his to own - it wasn't your fault you trusted someone and got hurt. I know it's bad - but you didn't deserve it.
He isn't every future boyfriend you will hopefully have. Remember that - he doesn't represent anything but himself.
