Breadcrumbs big enough to be a sandwich :(

My most recent ex is a fucking breadcrumb machine. Last night she sent me this:

"Hey TK, I want you to know how proud I am of you for how far you've come in the past 2 months. I am also so sad that it took us breaking up for you to finally make these changes. I'm heartbroken that we could have been like this together. Just in case you ever doubted it, I want you to know this. I love you."

It was so big a breadcrumb it could have been a whole sandwich. She knows I miss her and love her, but right now I'm pushing forward with NC. I don't know what she was hoping to get in return, so I just simply replied with "I don't know how to respond to that right now" and she didn't send anything else.

But it still stirred everything up all over again. I didn't sleep last night and I won't again tonight. I just want to call her, but I know that right now I need space and time.

This is just more of a rant - I'm such a wreck, every time I start moving on she brings me back. If she loves me and misses me so much why are we doing this? :(

Edit - I didn't reply to the pictures she sent me, still working up the mental fortitude to block her.
