How do I stop thinking and reaching out to my ex?

My ex already wants nothing to do with me.
I still have his photo on my phone.
I feel nothing without him.
He’s my everything and toxic.
I can’t stop thinking about him.
I hate him and I love him.

HELP!

He broke his promise he wouldn’t leave me.
He accepted my flaws.

I’ll never find someone else like him or better.
