D - You did so many things right! Letting her know that using text to discuss the kids visitation wasn't appropriate. Good for you! Being honest about how you're feeling. Another atta boy! Not slamming, barring, and locking the door - but realizing you've done all you can. So very proud!
I know you weren't after praise - but your tone sounds a bit glum. I know this wasn't what you wanted. You haven't given up, though. You've just decided to let her follow the path she wants to see where it leads. D, you can't be much more loving than that.
You've got so many things going for you right now. It's just hard to see because of the loss of something so huge, something that meant so much to you. But you have one thing in the minus column, and hundreds in the plus. How's a little perspective?
I plan to stay here and keep working on myself and helping others the best I can. We're meant to pay it forward, I believe. Look at all you've learned and how much you have to share! Something wonderful is coming your way...I feel it in my bones.
