Missy, he has really put you through the wringer over the past several months. I'm happy to hear you're moving forward. His behavior has been deplorable and there is no doubt that you have given this your all. If you have a lawyer, I'd send him a letter (registered mail) and an email cc'ing your attorney informing him that you will only communicate with him via your attorneys. There is to be no more phone calls, no more house visits. You will meet him at XYZ to transfer your son (if he's seeing him) and again at XYZ when he returns him. 74 phone calls & emails IS NOT OK. Him sitting outside of your house IS NOT OK. HE did this, not you. I'd get an OP. I am not totally for OP's during divorces, but he has problems. Between his past 'incident' and last night's behavior you should easily be able to get one. You can do it ex parte, he doesn't even need to know until he is served with the order. The police officer who serves it will probably spell it out to him loud & clear, too.
Please be careful. You keep doing what's best for you & your son, as hard as it might be. :huggy:
