Falling in love with my ex

And I’m not sure how to tell him. We broke up a year and four months ago and have been friends since and we’ve been hanging out a lot more frequently. He’s even started kissing me on the cheek/forehead again. Unfortunately, we’re so much alike I’m not sure it’d work out again because we are equally as stubborn. And the worst part is I broke up with him. So now i’m stuck here feeling stupid not knowing what to do 💔
