Haven't rtft so apologies if I've missed crucial info but based on your origional post. I think it depends on circumstances.
If you're in your 20s want kids marriage etc then yes you did the right thing, it's not going to be that.
But speakng in my situation, 40 something, don't want to do kids and marriage again then that scenario works.
People always say it's not going to go anywhere but where does something need to go. If you're happy with how it is then surely it's where it needs to be.
I think commited relationships come in all different shapes and sizes. There's not one model fits all.
But in any case he was happy with the status quo, you wasn't so you ended it. As long as you did that so you can move on to be happier single or find someone on the same page as you then you did the right thing.
If, on the other hand you did it to push for something more, something else, something he doesn't want to or isn't able to give. Or you did it because what you had just didn't match others expectations of what is right and wrong then you may have made an error of judgement, but only you know that.
Oh and fwiw, I'm not looking to start a relationship anytime soon, but if I was I wouldn't want to live together, or any of those other things I've done a hundred times over. I would also rather go with the stance of quality time over quantity of time. Doesn't mean I have deep seeted issues regarding commitment. I'm fully able to have a commited relationship but that doesn't mean my idea has to fit in everyone else's box.
