Move forward geng.
Perhaps something remains unsaid for you, even now. Perhaps that’s why your feelings remain so strong.
Perhaps part of you holds out hope you could get back together again. Perhaps you need to admit that and let go of it.
Maybe you fear you won’t meet anyone else like your ex. You won’t, but you will meet someone. Just they will be different.
So, instead of trying to quash emotion, ask “Is it possible for me to feel like this and still be okay?” Because your heart is stronger than you know; it is designed to handle being broken.
Go in, sit down, see what happens. Give your heart the chance to say everything it wants regarding the relationship and whatever is entwined with it. What emerges may surprise you.
Give yourself a new and different opportunity to leave it behind.
