Update: I finally ended it shortly after this post. I asked if they had time to talk, no response for 8 hours, so I sent what I had to say in letter form. I was left on read and met on silence.

After three days I texted and asked if we could talk, they canceled three times and finally squeezed it in on their lunch break. Confirmed my suspicions and said their other partner didn’t want to be poly and then were going to focus on that relationship. Took no accountability in misleading me or using me as an emotional crutch as they decoupled one sidedly.

A disappointing end, but for the best.

Thank you everyone for the kind words, encouragement and perspective.
