So I recently broke up with my fiance because she wasn't taking care of herself and was emotionally damaging me, and we want to get back together when we both have our mental health under control. I'm looking for suggestions about how I could put some goals in place that have to be met before we can consider getting back together. 

For some more context, I felt like I was on top of the world early on in our relationship and I cannot imagine a future without her, but things spiraled completely out of control after I broke up with her and it's left me at my worst. I have a diagnosis for bipolar 1, but my psychiatrist isn't completely certain that that's what I have. For this though, it works, because my symptoms mostly make sense with that. 

Ideas I already have are that I can set some sort of goal based on going to the gym, since that is something I do when I'm healthy. I can also require myself to be a certain number of days or weeks clean from self harm. What ideas do you all have? Feel free to ask questions if you need more information, and if you have milestone ideas for my ex too I will share them with her.
