Be strong, honey. You did the right thing, based on your earlier posts about his exploits, and you can now get on with meeting someone else yourself.
You have every right to be proud of yourself. You made a decision that will benefit you far more in the long term and now you can get on with the rest of your life. It may be hard at first, losing something you invested part of yourself in always is, but take what you learned from what you had, and the good feelings you gained from that, and know that you will have that again, if you want it.
*big squeezy hug* You'll get through this, Brady. And find a guy that's absolutely perfect for you honey, with whom you can be happy.
And if/when he meets someone else, remember how much you want him to be happy rather than how that someone else isn't you. And if he is happy, then he has what you wanted him to have, and you can concentrate on getting the same for yourself.
You have all the support you ever need, honey. *extra hug*
