How do you know when you are truely over someone?

You never really 'get over' someone you love. If they hurt you, then that hurt becomes a part of you, a part of who you are. But people adapt. In time, the hurt dies away. When you find yourself falling for someone new, then you know that you are ready to love again.

They would be friendly and want to make friends to you

it's hard and even with a one year and have I'm not over her. I'm try to find a way to get her of off my mind. nothing seem to work for me.

When you can wake up and go to sleep at night with that person not in every thought. When you can love someone else.

When you don't think about them everyday. And when you can be with someone else without comparing that person to your ex or wanting to be with your ex instead.
Also when you think about your ex asking you out and know in your heart that you would say no... and mean it.

Truely over someone...
Well, you can get over the dead (ex-loves), while ready and willing to date again...

Over the living-ex... Easy.., when your hatred against mean and hurting ex has cooled enough that has enough cool mind to find "better individual" as a replacement...

I had difficulties to get over my first as she had died,
but getting rid of third girlfriend was more like a relief...
However, even soon after would have been ready to date again.., I started to pursue my career... Still single...

And I can tell you this. It is really easy emotionally to get over those ex's who have been hurtful or deceiving, just needs to learn to hate that individual... And even love can be converted to relentless hatred.... And it actually to makes feel good... But "all good" individual would be difficult to forget... I have noticed this...

i wish i knew.haven the same problem my self

when you see them, and you have no desire to kiss them, or even hug them. this just happend to me, a relationship of mine ended badly and out of the blue, he texgted me explaining all his regrets. we hung out a day later and i realized i didnt like him like that at all! it was probobly due to the closure i had, but i think thats when you really know

I am going through this now and it is awful. I wonder myself.

if u start to be interested in other people and think about them a lot. and when you can talk to your ex without any akwardness.
