<human>: Give me a shortened version of the text

My ex and I have been friends and family to each other for years and have a dog together. We have lived together for a few years now. 

We ended things on good terms - nothing horrible happened and we want to stay a large part of each other's lives - it came down to him doubting we could fix things whereas I had hoped we could.

After a few weeks I started finding some new activities to enjoy, I was going out with new friends, and focusing on myself. Then he told me he's found someone knew and thinks she could be special.

It's been a little less than 2 months after our breakup and she's already calling him her boyfriend. I want him to be happy, but I wasn't ready to handle all of this at once and I'm not sure how to.

I just want to skip ahead to a few months from now when I'll be happier and more past this. I know I need to get out and start living my life again, but I keep being reminded of her. How do you start the healing process so you can start living again? How do you get past that initial rough period?
<bot>: Over 6 year relationship, broke up on good terms, want to stay friends, ex has a new girlfriend less than 2 months after / Any advice from similar experience? What would you do in my situation to start healing?
