How do I stop loving my ex?

I thought after all this time, things would be easier. It’s been seven months. And I still cry over him sometimes. Sometimes I hate him, sometimes I wish I could have him back. I don’t know why he left me, but he had a new girlfriend immediately after we broke up. Of course I’m angry and I know how much of a dick he was.. but it doesn’t stop me from loving him. He definitely love bombed me in the beginning. We talked about our wedding plans and had the name for our firstborn daughter picked out.

I don’t understand how he moved on so fast but I can’t.

I tried going on dates, but other men just make me miss him because I find myself looking for him in other guys. Dates just make me miss him. It’s easiest if I just stay single and don’t try. I’m 27 but This was my first love, my first heartbreak. I’ve never been through this before.

When will this pain end? How do you stop loving someone you thought you’d spend your whole life with?
