I haven't posted on your thread yet, but this caught my eye.
Mmm, I wonder if she thinks she can replace you as the boys mother too? Men are easy to manipulate, but one's children aren't that easy to get. You gave birth to them, and have nurtured them all their lives. So, if you do want to respond, tell her this, "you will never and could never be my kids mother, I gave birth to them and H was there, and it was a wonderful moment in our M, and no-one can take that away from me, not even you - NOT EVEN XH. I'm not sure of your motive for texting me, but know that it doesn't bother me one bit, in fact, I feel sorry for you." Then, when X and OW comes to pick up kids, you go to the car, greet her and X in a friendly manner, tell her "no, no need to get out the car", and then kiss the boys good-bye and say "have a good time with your dad," turn around and walk away. (This would show the boys that you are trying to be amiable. Try and have witnesses to your interaction, and do this every time from now on.) I would love to know how she reacts to that. In fact, maybe you should provoke more texts to show in court. Well, just some suggestions and thoughts.
But, dating might be a good way of getting over your X, if you aren't already over him.
