Glad to hear you feeling better Ziggy.
Yes, focus on yourself first and foremost.
Get distance from this whole situation. If she is still texting you and thinks it's ok to text you, there is not enough distance yet.
Focus on you. Get back to what you truly want and then that person will come into your life.
I am doing this right now. I don't want to date anyone...my mind and heart are still caught up in too much crap. I know I will get out of it, but now it's "me" time.
Is it finally "you" time Ziggy? I hope so. ;-)
