I can totally empathize, I have up my dream job moved across the country had 4 kids and totally dedicated 10 years of my life to someone who sauntered off an made another woman pregnant, after saying he couldn't handle the commitment.

So I know angry, in fact it wasn't anger it was all consuming fury.
I would actually shake if I thought about seeing him again, and what I would say and do.

I felt I couldn't physically contain the emotions.
I wanted to physically hurt him.
Eventually though I realised I was just as angry at myself, and that the more time I spent obsessing over revenge, the more he was winning.

What your going through is normal, a totally acceptable part of grieving.
I don't know if revenge will make you feel better, I never got the chance.
I do know he never wasted a second thinking about me after he left and wasn't worthy of my time or effort.

It's true what they say, success is the best revenge.

I hope you can work through this, however that manifests itself.
Keep venting, and letting it out, hopefully one day you will find you forgot to even think about him.

Take care.
