So sorry to hear that things aren't working out, but I can see what you mean when you say your girlfriend's demands have just gotten to be too much.
I certainly respect your choice to visit or not visit Polyamory.com, but I hope you will still visit us and say hello. Even if you aren't in a poly situation and even if you don't plan to be in one, you're still welcome here in my opinion.
Whatever lies in store for you in the future, I hope it is peaceful and fulfilling, a welcome break from the drama that you have endured.
With respects and regards,
Love means never having to say, "Put down that meat cleaver!"
