I am sorry that your h is still monstering, but I want to offer you just a wee bit of advice. From this day forward, any time you have to pay for something or provide him w/information about something, i.e., for example the EZ Pass tag, take a photo of the items. That way, if your h is acting like a mule, just pull up the photo and send it to him if the items are in your name. Then, if he's got an issue, he can stick it where the sun don't shine.
As for the date of September 1st being the day that you send him money...true, at the strike of midnight, August 31st rolls into September 1st...but that doesn't mean you have to get up at 12:01 a.m. and send him money...you have the full 24 hours to do so. Your h is attempting to bully you and scare you into doing what he wants. He knows that he can get away w/it. I might be wrong, but you can't usually schedule court dates over a weekend or a holiday weekend.
Since it appears that you are having a difficult time w/your cash flow, have you given any thought to filing for bankruptcy? I realize that this is not something you want to think about, but it might help you w/some of those bills, etc. that keep hounding you.
I know things look very bleak at the moment, but you've got to stay strong and not allow this man to scare you and beat you down.
If you ever notice, when we have terrible natural disasters, God tears everything down to the ground and then allows us to rebuild. When this happens, generally the towns and cities come back even better than before. This happens w/some marriages. I'm not sure that this will happen w/yours because of all the damage he has created. It's okay to stand for marriage, but it's not okay to stand for abuse and manipulation. Gerda, I'm going to be perfectly honest w/you, your h is not going to go away quietly. He strikes me as someone who is going to bully/manipulate you even if you file for divorce and it is granted. There are some that you can't please no matter what. Do the best you can when dealing w/him, but I would try to refrain from as much contact w/him as possible.
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.
