My girlfriend left me for someone else but tells me she still cares about me, but doesn't love me. She was in tears when we split and didn't want to delete my number or off Facebook. I have absolutely no contact now. Hopefully, she will realize what she's lost.

No, you have no contact so that YOU get over her and move on. You learn to not care what she thinks and if she never knows what she lost, you don't care.

It sounds like she just had hard time telling you and was trying to make it easy, Accept she is gone, don't care what she thinks and move on with your life

If she doesn't realize what she lost, you should be doing your own thing.

She left you for someone else.

That's the ultimate slap in the face. As far as Im concerned.

Why would you want to know more of that? Yuk. Ewww. What, for later?

That's crazy talk.

Let her be with who she wants. And you be glad to be rid of girls like her.

There's cool & good ones out there. Find them.
It'll be fun.

Stick with NC. No FB, texts, etc... Everything.
Don't respond. From now on.
