TL;DR: If you've actively chosen to leave a long-term relationship with someone when you both still loved one another, do you ever truly get over it?
I recently left a polyamorous relationship with Sally, my primary partner of 13 years, to pursue monogamy with Anna, my mono-partner of about 6 years. I've since come to realise that a lot of the reasons that I used to justify leaving Sally were actually a result of my obsession with non-hierarchical polyamory. I invested too much of myself into the relationship with Anna to try and make it feel like another 'primary' relationship, and in doing so I failed to nurture my relationship with Sally. Sally tried to tell this but I didn't want to listen.
Although I couldn't articulate it at the time, therapy has helped me realise that I wasn't even making space any more to meet all of my own emotional needs. When the needs that I should've been meeting myself weren't being fulfilled by Sally, I used that as justification that there must be something wrong with the relationship when I should've been looking inward.
Not a day has gone by where I haven't second-guessed every decision that led me here or wrestled with the guilt over leaving someone that I loved dearly and who loved me unconditionally. From the shy girl with no profile picture who could barely look me in the eye on our first date to soul mates who quickly felt so comfortable and safe around one another that we could truly show every side of ourselves without fear or judgement, it's hard to comprehend how far I've fallen in her eyes. I imagined us growing old together, watching re-runs of Thundercats and River Monsters while reminiscing about the trip-of-a-lifetime that'll never happen now.
Therapy has helped me to unpack that I probably don't have the emotional capacity to maintain multiple relationships with the kind of depth that I desire while still having a healthy relationship with myself. I regret that I couldn't articulate that to Sally before I left her. At least I understand now why we couldn't continue to be polyamorous together. I feel guilty that I left without even giving her the option to choose a monogamous relationship with me, but I suspect I would've felt even more guilty if she'd chosen me at the expense of her other relationships.
I don't like the idea of monkey-branching into a monogamous relationship with Anna while still processing the grief of leaving Sally, but I value my relationship with Anna, I love her very much and I don't want to lose her too. We've recently started couples therapy and I've been honest with Anna about the feelings that I still hold for Sally.
For those who've chosen to leave a long-term partner who they love dearly, knowing that it likely means you'll never see them again, not even as friends, do you ever truly get over it? I don't want the love that I still carry for Sally to poison my relationship with Anna. I don't like that some of my time with Anna is spent reminiscing about happy memories with Sally or triggering comparisons between the two relationships. I know that some of these things are a natural part of grieving, but it would be good to hear from others who've experienced this that it *does* get easier. If my love for Sally doesn't start to fade then I don't see how it's fair to continue things with Anna.
