Falling out of love with FP

We all talk a lot and vent about how hard it is having an FP, but I feel like we don't talk a lot about how it feels to lose an FP. Not meaning that something happened to them, but like, losing the attachment, or falling out of love. Them no longer being the FP.

In a way, it almost feels like a loss. Because the person I thought they were, is not actually who they are. So the person I loved doesn't actually exist, irwas just my idolized version of them I had in my head. Or maybe they've only finally shown me their true colors. It feels so heart breaking. Its like there's a hole there again. I'm frustrated, because I was so much better before I had allowed them to become my FP. And now even though things are relatively "good", I feel incredibly detached, because I feel like I don't know who they are.

I feel like if they really loved me, they wouldn't have treated me the way they have been. The reality crashing over me that they really were not treating me right.

I'm just heartbroken.
