Confusion. Heart broken.

So I could use some opinions and advice. I was engaged and we broke it off in the summer of 2015. He's a big drinker and caused a lot of arguments. Never sober when he was home from work. We didn't have quality time together. He begged for me back for months but I knew nothing had changed. I started seeing someone but he broke it off with me.
For the past week I was hanging out with my ex fiancé. Who has a new gf for one month and is moving her across the country to live with him. He's finally now realizing he can't be drinking like that and it breaks my heart that someone else will reap the benefits of all my hard work. I feel like he's settling. It's pretty obvious without being said that we still care for eachother. I'm not trying to interfere with what he has now but do I hold any hope he'll come back?
