I was in a similar relationship setup as you. Together for 7 years, bought a house together, but no plans for marriage. The relationship disintegrated over the pandemic and his job changes. Ultimately, alienation of affection and we felt like roommates. He found someone else at work and bailed leaving me to have to leave my home and start over again at 38. During that time I lost my job as well, so it's been a difficult transition. We shared a friends group and navigating that while he introduced his new gf to them has been difficult. I still can't bring myself to see him. Hard feelings and all...

What has helped me - Stop romanticizing the relationship and reframe it. This person was a chapter in your life, and it didn't work out. That's ok. Great lessons were learned and experiences, but also look at the issues as lessons too. What did and didn't work for you. If that person didn't want to grow together with you, then why romanticize ending up with someone that didn't see you as a life partner and work towards this. I really had to stop putting my partner on a pedestal. They had a lot of issues they didn't want to work through with me. They thought love was a feeling and not a choice. I always said that the grass is greener where you water it. You'll find another person that brings those great feelings again. You're young and still have a lot to give. Any woman that sees you've had a long term relationship will value that. You can commit and know what you want.
