What made it easier to walk away?

Hey guys 💓 I really need some help here. I’ve been in a relationship for almost 3 years and the last year has been very bad. I’ve tried to hold on in the name of sticking it out and going through rough patches. But I’m starting to gather it’s not enough. I have more bad days than I do good. Can’t even remember the last time I felt very in love. I love him very much and it’s been a big struggle to even think about walking away. But I’m starting to think it’s time. We just aren’t what we used to be. And live alone isn’t enough. Any tips on how to ease into without just back tracking and changing my mind?

P.s this was without a doubt the person I saw myself someone the rest of my life with. I will definitely be single for a couple of years just trying to get over what we had/have
