<human>: Condense the text into a few key points

So a little background on us. We dated for 2 years. We broke up around 4 years ago because I had trust issues and self esteem issues.

I'ved dated one guy seriously(1.5 years) since him, but I still can't get my ex out of my mind, in fact it got so bad I ended that relationship. I believe  I've matured a lot over the years, I've been through a lot since then. I've learned how to love myself, which I think is a huge step toward being able to love some else in a healthy way. For the past year I've  working out and eating better.

I need help on what to tell him to show that I've changed and that I'd be interested trying things out(slowly). I just don't know how to word this...
<bot>: I want my ex to know I've changed and want to try and possibly try to get know each other again/possible date.
