we’d been dating for 9 months and I was convinced this was my first healthy polyamorous relationship after a pretty messy first few. Yesterday I ended things with them because their depression was consuming the relationship to the point where there wasn’t much point continuing. At this point they flat out told me they will probably never gain feelings for me but are in love with their other partner and are probably just monogamous since they’re clearly not very good at juggling multiple connections. I could tell they loved their other partner more than they loved me but I thought that it was a case of taking things slow and allowing the relationship to progress at its own rate instead of comparing it to someone else, but i guess i was wrong about that. i feel totally blindsided by them admitting they’re monogamous after this long together. I’m gonna take a break from dating and figure out what patterns i have going on that leads me to these breakups but for now i feel so bummy. i would appreciate the support a lot thank you :(
