NRE - rupture and repair

One of my anchor partners started dating two new people.

They get intense NRE forget dates with other partners, their sex drive is primarily focused on their new partners, they have been talked to several times by many people. They have kinda abandoned themselves, don’t hang out with their friends much anymore. They mostly only engage with the two people they have NRE with.

We had a really lovely relationship ones that included our friends, family, and metas.

I made a choice to take space and a step back with them. I felt very disrespected but the amount of times they flaked. Previously to the NRE they were a great partner. We are in the same polycule and still kind to each other.

Curious to hear from people who might have blown a good relationship for NRE?
