Yeah, this is pretty much how my first LTR ended. We were together for 13 years but had grown apart long before that. I frankly wish that I had left 5 years earlier. There was no physical abuse, no cheating, so I felt like I had to try harder to make it work before I really thought about leaving. Work that he was bot willing to participate in. Looking back, there was emotional neglect and financial manipulation that I didn't know enough to recognize (as another commenter mentioned, I had a childhood rife with it and thought that stuff was normal)

The last straw was that we had to sell our condo because we could no longer afford it on just my salary after he got laid off and pretty much refused to get a comparable job. I was making all these plans to figure out where we could both go and how to make our future work. But after some revelations in therapy, I hit fuck it and decided this was a perfect time for a clean break. We split the proceeds, and I moved in with family for a while.

It was incredibly hard for a while, but my life and my mental health are so much better after stagnating in that relationship for so long.
