How do I treat my soon-to-be ex?

[NotReadyToQuit]

Hello again, it's been a while since I've posted on here. I had a thread a while back called "help save my WAW" (not sure how to link it).

Quick background - 9 mo ago W told me that she wasn't happy and wasn't in love with me anymore. She thought we were more like good buddies than lovers. We tried counseling for a while and had a couple "lay it on the line", "heart to heart" discussions (mostly on my part), but she finally told me that we didn't have anything worth saving and that she wanted a D.

We now have been living separately for a little over two weeks, and we are signing the D papers this evening. It all happened a little faster than I expected, her mind is made up and she seems to want to get it over with.

I've read all about 180s and GAL and focusing on bettering myself, but how do I treat her? Do I still stay in contact? I still love her completely, although she hasn't supported me or even really showed that she cares about me for a long time. I know I deserve better and that this is probably for the best, but she's been my best friend for over ten years. I can't just drop that and walk away. The problem though, is that I don't think I'll be able to get over her if I don't.

Do I help her when she asks for it? Do I still do favors for her when she needs them? This is what I'm struggling with. I don't want to close the door forever, but I also don't want to be her crutch and let her walk all over me. Any advice would be greatly appreciated. Thank you.
