I think the fact that it’s over is in some way evidence that you couldn’t have saved it. Because it takes two to save a relationship, every couples counselor will tell you this immediately. You don’t give much info about what happened, but in virtually every circumstance, if both parties are willing to stay and work things out there is a chance to save the relationship. But if one party is unwilling, the other party unfortunately can’t make up for it by being extra willing, no matter how much effort you put in. This is an unfortunate constant of life. You can and will find someone who will want to stay and work things out no matter what happens, I’m sure of it OP. Three years ago I was a frequent on this sub, blaming myself for a breakup to the point that I was seriously suicidal. I know now that there was nothing I could have done to save it. Now I’m in a very happy and stable relationship that I know will last because I know my girlfriend will always be willing to put the work in (barring infidelity or something, which I know I will never do). You’ll get there too, probably in less time than you think. I hope this helps
