Her wanting to be friends is a good thing... work with it, (be friends & family) but I think it's best to drop the flirting or anything romantic. It only makes you look weak and pathetic, and pushes her away because she's not feeling it for you right now. Doesn't mean this can't change, but you have to be calm, cool and confident. Not easy right now I know, but you can do it. Do fun/fulfilling things for yourself.

Definitely no more relationship talks for now. You need time for her perception to change... you don't want to force a decision right now.

M: A really long time.
Crisis: 5 years.
She's still worth it.

Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
