I hate to say this, but I think you spurred him on when you sent him the text earlier this week about what you would like in the way of child and spousal support.
Unfortunately, the way he's viewing things is that you are more than willing to tell him what you would like to receive in the way of support money, but yet, you are also telling him what he can or can't do w/his child when he comes to visit. He's tired of an eleven year old child telling him not to come or she doesn't want to see him...but he's paying child support and feels entitled to see her whether she likes it or not.
Unfortunately, it's not going to get any better and that's why it's important that you get something put in place legally as soon as possible.
No matter how you slice it, it's going to be a tough day for your daughter tomorrow. Please try to remain calm and civil. How you deal w/him in her presence will be important.
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.
