Re: I'm a girl-how do i win his trust back?!
I'm just so happy to see that you are really learning your lesson from this. It will help you grow as a person and be a better partner for someone, though I am sad for you that you have to go through all of this pain. LockDown is completely right about you finding out for yourself WHY you went to dinner with your ex. We never really get over our ex's, at least not without a lot of time passing. That is the main reason for no contact.
Honestly if you are still in his life I think he likes you and you will probably get him back. You have done your groveling and now you just have to wait.
It is a funny thing, this love.
It seems to me you may have been after closure. You really don't get closure from a relationship until a while after it has ended in my opinion. It always helps to talk later with the person about what went wrong after everything is no longer fresh and it isn't so emotional.
