“I've been doing a lot of thinking, and while this is NOT what I would have wished upon anyone, I have come to the realization that I WILL BE OKAY no matter what happens. I still don't want to separate, but for now there are some things I want to work on, just for me. In short I want to strive everyday to be the best version of myself possible.”
" W a separation is not what I want but if that's what you want I won't stand in your way"
Short and to the point. I see what you are trying to do but words mean nothing to her right now. She wants to see actions with you. I think a separation is good for you to show her you can stand on your own two feet.
Be strong and keep your emotions in check. This is the first half mile of the marathon.
