I swore up and down to anyone who would listen that my ex was "the love of my life who I'll love forever!!!!!!!!!1111" and I believed I would never get over him and would never stop loving him. And I would gladly take him back at any time, no matter how long it took. Then a funny thing happened. A couple of years had gone by and I ran into him. And...felt nothing. I thought, this can't be right! So I deliberately exposed myself to him again. Still nothing. Then, oh happy day! He contacted me and asked if he could see me. I thought, well, here's my chance! So I went out with him. And found him to be insufferably boring. So I tried sleeping with him. Ugh. That was even worse. I got zero enjoyment or pleasure. Zero passion. So the next time he contacted me I turned him down.
I would have bet my life on leaping at the chance to reconcile with him and would never have imagined I'd turn him down, but I did. I did not and do not "love him forever!!!"
You'll get there. And when you meet the right one you'll wonder what you were thinking.
