<human>: Give me the gist of the text in a nutshell

My ex and I have been broken up for about a month. She fell out of love. She said she felt like that for several months before the break up, but was slow to bring it to my attention. The more attention she brought to it, the more appropriate my reaction was, but in the end, neither of us fixed it fast enough and it was too late for her. 

Now we are living separately. We were together for 3 years (living together for a year and a half) and we have a 15 month old son. She is currently seeing other people and says she hasn't gotten serious with anyone but 
definitely likes the guy she is dating right now. 

I personally have made several changes and have realized what I have lost with her gone. Both of us hate that's what it took, but I "get" what wasn't working and what will work if we got back together. I have made strides in several areas that are important to her and I'm trying to focus on being a good dad when I can.

What are some general tips that could help bring us back together in the long run? I'm not searching for a quick fix and understand she needs space, but how do I help her see us as the "right" choice in the future?
