Renee, Your h most likely had a flu bug and something you have to let go. The ow most likely knows that you and/or your son are reading her page and put it out there for all the readers to see. These op can be quite spiteful in the best of times and that's why you need to learn to let it all go. Yes, it hurts, but you know what, let her deal w/him when he's sick. Who knows....he could very well be a sorry type of patient when he's sick.
Affairs die their own natural death. No one can tell you whether it will last or not, but I do know this, the more you question him about the relationship/ow, the more determined he will be to stay w/her and defend her. That's why it's important that you not even bring up the issue of what he's doing and w/whom right now.
Renee the protection order was most likely done because of your calling and using excuses to call him. He wants peace and quiet and he wants his independence. He's told you in a very real way to leave him alone. That means...finding a way to live w/o him in your life right now. It's time to figure out what you are going to do now that there is no contact.
As for the hang up calls...most likely him, but I wouldn't put it passed the ow to call just to get you to call and violate the order. Don't even think about calling him. If he calls you, hang up because it's in violation of the order. Do not be tricked into getting arrested because of what he's put in place.
I'm sorry it's come to this, but he, in his own mind, felt that the only way to get you to let him go was to have this order put in place. Now, you have to find a way to go on w/your life, but leave the door ajar just in case he opts to return.
Don't worry....your h is okay. God takes care of babies and fools.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
