Welp, I am newly single after a year long relationship

I was the one that ended it and I expected to not feel as many things as my ex, but shit I didn’t expect to feel numb. It’s kinda freaking me out.

What am I supposed to do now? What is life now? My ex sometimes told me he thought I only dated him because I just wanted a relationship. I keep wondering if he’s right and if there’s something wrong with me and if all my future relationships are gonna end like this. I just feel deflated and lost.

Thanks for listening to my lil rant
