Hi, I learned something I'd like to share with you, if you want to hear it, sometimes things don't work out...even if you REALLY love someone there is no guarantee of anything.
Its ok for people to have different likes and dislikes, someday you may have to give someone else the same kind of news, because you found someone else that was a better fit for you.
But, in the meantime, don't create multiple relationships, which is what it sounds like he did. You can't control what other people do, only what you do, hold off on getting intimate until you know you can really trust someone, because if you get news like this, it hurts so much more than if you were keeping it on a more friendship level...without sex...
