This is a familiar story that most of us have been through...sadly!
But if you really did feel love then you found something real...at least you know you have that capacity in your heart and have felt love. In time you'll meet the right one. Have faith and keep an open heart...the only way to find love is to have your heart open. No sense in vilifying him....you likely still care.

It hurts to be diminished, abandoned, lied to. Now you know and know more what you're hoping for. Keep your bright hopes and try to keep your heart from becoming cold. It's hard to recover but you will.

The hurt and pain will will go away but the memory of it will not. It may never........This has got to be the worst pain ever finding out that the one you love is cheating on you. Time is a good thing right now for you as they say time heals all wounds including the heart.
Dont let this make you hard or against love. Love is a wonderful thing and can be described in many words.
Love is also a chance we have take. We take it every time we fall in love. There is allways a chance we will get hurt but we have to continue to go back and try again. The reason we do is because once we find that special some one the world is a wonderful place to live. You can get no better high than you can off of love. So hang in there and be strong let this pain be a tool for the future...take care and best wishes
