A tiger doesn't change it's stripes. If he left you once it's not surprising he did it again. You aren't a fool or stupid. You are learning how to live and we all have sad stories but don't let that define you. I wouldn't put any stock in this fellow. Move on. You are too sweet to be treated like this. This is not what love is like. Chalk it up as a learning experience and know you are too good for him. Really.
