You know for a fact you were shortchanging yourself by staying with him. You're certain there's someone else out there who'll love everything about you in ways that he never did...
But you're struggling. You put so much effort into loving a person who didn't love you back and you don't want to admit that all that time was wasted.
You know that relationships are never easy or perfect so giving up was never an option... until he left.
You loved every part of him, good and bad. Not only did that love not fix the problems you had as a couple, it's made it terribly hard for you to let go.
Your heart wants nothing more than to win him back but your mind is telling you, "he left, move on." You meet a great new guy but just can't find it within yourself to like him the way you liked your ex.
Your world is shattered and you really have no idea where to start when it comes to living again.
But you'll do it anyway.
You start focusing on yourself more, learning what life is all about and remembering what's important in relationships.
You start realizing that yes, love is complicated, but it's not the only thing that keeps people together.
Just because you can't put anyone else above him right now, doesn't mean you'll always feel that way.
Just take things day by day; live your life and mourn the loss of your love.
Eventually, it'll get easier. Your heart will heal.
When it has and you can finally move on, you'll be free to find the person who won't ever leave your side.
