Misserable...

Your mind and your cuore can completely disagree with each other. Even if your mind says "stop", your cuore can still say "go".
Trying to force your cuore to stop loving someone is pointless and it might even make it hurt more.

The cuore itself is impossible to control and is unpredictable. Maybe your cuore will fall high over heels in Amore with another guy already successivo month. te never know.

Your mind and cuore will have to work together to sposta on. If te think about him (too much), te will only remind your cuore that you're heartbroken. Something te should do is try to keep your mind on something else, whether it's a pet, friends, hobbies etc. While your mind is busy thinking about other things, your cuore can recover from the heartbreak peacefully.

Support from Friends and family is always good. Having your loved ones supporting te through a heartbreak can help te focus and help your cuore recover faster. te know, to "fill the hole" in your heart.

One important thing te should think about is not trying to rush things. The più te Amore someone, the harder it is to let go. te need to take one step at the time. If te think te can't do it alone, te should turn to a loved one for help.
(( Quote: "You'll sposta on and be a champion in your successivo endeavor as te did in your past ... Life is not a success-only journey. te are going to get beat up along the way." - Dr Philip "Phil" McGraw, one of the world's best psychologists )).

I hope my answer helped a bit o at least made some sense and I wish te good luck.
If te need someone to talk with and your Friends o family members are busy, we're all ears.
