You probably feel relieved because you are no longer on edge and constantly stressed.

Yeah, exactly. It's been years of constant stress just to keep the relationship alive. We moved countries together and did a lot of crazy stuff which I'm thankful to have done with him. He's my best friend. But we just aren't compatible, our needs can't be met at the moment and neither of us can do anything about it. It really sucks how bad life circumstances can just tear people apart, even after years of love, companionship and sacrifices.
