What ever became of the Target incident? Why, after THAT, did you not start doing drop-off/pick up inside somewhere with witnesses? That's what I do, I do drop off/pick up inside of a grocery store, half way between ex's house, and mine. I don't speak unless I have too(ok, once I muttered to myself and he took offense to it) but I haven't been touched by him in this time.
THAT NEEDS TO HAPPEN WITH YOU! This is what, your 2nd or 3rd arrest for this? Obviously changes need to happen, and happen NOW. Not two weeks from now, not a month from now. Immediately. CALL the domestic violence hotline, i don't care if you're embarrassed because you used to work with them. You and I separated at the same time, and while my divorce isn't final either(mostly because I don't have 3k to file, I will very soon though) my life has become much calmer than yours, because I took a stand and put a stop to it.
it's tough love time dear. Stop being a doormat. Teachers can get hired anywhere, do a quick google search.
