Kimmerz, Don't lower yourself to his level. Keep in mind that he is texting you about gifts for your daughter. He only has a week left to do his "Santa" shopping and it must have struck him today that it's a week away.
I would roll all of your responses to his multiple texts into one text and let that be it for today and I would respond later in the day, don't do it right away because that's what he wants you to do.
Yes, when the cat's away, they come out to play. Also, the holidays tend to bring the crazymaking out to play as well. They want to "appear" as the best parent ever who wants the best of their children. Don't be surprised if he spends quite a bit of money on the gifts. Some tend to do that to impress others. I would provide him w/some high end gifts and see what he has to say about it.
I know that you are sick and tired of this nonsense, but right now, you have to consider your daughters and the holidays. You do want him to try to get something that they would like? At least he is asking and not just "assuming" on gifts.
Oh, yeah, the Thanksgiving situation is now history and it's been swept under the carpet by him...it's a new day, new holiday w/him. It's the mlc mind thinking. Hopefully he will settle down after the holidays.
You will never fully get peace while he's alive and breathing, especially w/having children together. The best thing you can do is learn to choose your battles w/this man. My advice, try to get through the holidays as best you can and after the new year, only respond to the texts that you feel are important. Consider him a lonely, insane man or teenager who can't let mom be, who wants to send you a postcard periodically from the loony bin. Once you can detach more and not react to his crazymaking ways, you'll begin to see the humor in some of his antics. Right now, you are still too up close and personal w/his antics and it is aggravating you. BTW, he knows that he's bugging the crap out of you because he knows you very well. Don't take the bait he's offering up in the way of getting you to react.
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.
