Does a wedding anniversary still count if you are separated?
He does not sound the least bit remorseful, in fact he sounds abusive to me.
You are still in shock. Take care of you! Eat, drink plenty of water, gentle exercise ... take care of your precious little boy.
Read the Healing Library (upper L corner, yellow box) and learn as much as you can about Wayward behavior.
I usually agree with informing the other spouse but as they are already separated and as your ex seems intent on making life hard for you I think that you should be as calm, collected and uninvolved as possible.
To answer your first question, yes, yes the hurt and confusion will end, you will find happiness, peace and joy again. I thought I would die from the pain, in fact I wanted to die and even considered suicide.
After a very traumatic and prolonged divorce I moved to another city. I remember one afternoon I was walking through a park on my way home from work, the spring had just started turning warm and I realised I had turned my face up to the sun and was smiling at the simple joy of being outside, hearing the birds in the warmth. It was a huge revelation to me at that moment that I was happy. There were still hard days ahead but I had turned a corner, these days I love my life, in fact the only time I've felt that pain again was when I stupidly took him back for a year(4 years later) he left me again for another woman and I learnt my lesson!
So again yes, it will go away, it may seem improbable and it will take time but you will recover from this jerk.
