<human>: We dated for over two years. I gave him everything I had emotionally, and felt like I was investing into a lifetime relationship. I've always been interested in pursuing an open relationship, hopefully with my partner. My Ex was adamantly against the idea. 

This was my first "real" relationship I've ever been in and I naively believed that we were not only both invested for the long haul (despite actually being married), but that we had accepted that successful relationships take compromise and a willingness to be flexible in both sides.

I realized I was very wrong after it was too late to repair the damages that I caused. I have been actively dating since being dumped, and am honestly becoming more convinced that I seriously fucked up with my Ex. Call it selfishness, naivety, or a mix of both, but I cannot escape the daily reminders of my unfortunate fuckup - whether it be real-as-fuck dreams about him, the constant reminders about our plans for the future, or my fucking dog that we bought together.......

It's still raw as hell. I'm trying to move on. I've found a Buddhist community in which I take refuge. I've thrown myself into my profession and education. I've committed myself to taking my medication and working with my doctors. But, I still feel like I'm stuck on some fucked up merry-go-round of regrets and sadness. I'm really just reaching out for some kind of support from anyone who has been in a similar situation. Seriously though, how do you move on when you *know* that the one person that you want to spend every day of your time on this floating rock in space with just doesn't feel the same way?

Can you give me the gist of the text in a nutshell?
<bot>: I don't know how to accept that my Ex isn't the person I'm going to spend my life with. How the hell do I move on?
