I have been good. I have been quiet. I have not ripped into you for what you have done to my daughter and my grandson. I even spoke to you nicely at Ethan's birthday gathering. For his sake, mind you...not yours.
However. If you didn't want a family, why did you lead my daughter to believe that you did? If you didn't want to have a child, buy a house, get a dog, why did you go along with Vanessa's plan? I know she can be very enthusiastic, but you are an adult. You could have said, at any point, "No...I don't want to do that. If that's what you really want, we need to split up, because I am not that guy." What is so very difficult about that? Compared to this situation, I mean.
Just who is "Celeste," anyway? Somebody you were seeing before you married Vanessa? Obviously, somebody you are seeing now! And what is with your telling my grandson who he has to love? He's four, for God's sake! He loves his mommy. He will always love his mommy, and she will always love him, whatever juvenile games you choose to play. Telling he he has to love Celeste because you do is bullshit. Telling him he doesn't love his mommy is emotional abuse. Does it give you a kick to think about him looking at Vanessa and saying, "I don't love you. I love Celeste?" How "middle school" is that? You are a grown man, for God's sake! Do you not care about the well-being of your son?
Here's the thing. This is how mature people who care about their children handle divorce...they put the child first. They do not plunge into new relationships within days of leaving their spouses. They do not expose their children, especially children as young as Ethan, to their new significant others and suggest that the new replace the old. They do not say bad things about their exes in front of the children, and they do not permit others to do so. They bend over backwards to assure their children that they are loved and will be loved and cared for by both parents, even though the parents are no longer together. They do not argue over money details, they work it out. They respond to communications concerning the children, rather than ignoring texts, calls, emails, etc.
You are not only an asshole for doing all of the above, you are a prime case of arrested development.
As for lying and saying it was Vanessa's idea to get the $1200 dog...sorry, Mike. I know my daughter, and I know that her preference would have been for a shelter dog, not some expensive puppy-mill purebred. Do you think that, just because you say it, you can make it the truth? Not so. Your mama may believe you, Celeste may believe you, but I know you for the lying cad you are. And I will make sure that as many people as I can reach know you for what you are, as well.
You need to discuss, agree on, and sign the parenting plan. Your divorce will be much more expensive if the Judge has to work that out.
Speaking of your divorce, it has been over two months since you left. Why haven't you filed by now? Is it because you are just toying with Celeste, the way you toyed with Vanessa? As long as you are not "free" (cheap, maybe), you can't be expected to make promises to her, now can you. God! She must be dumb as dirt to believe in a lying jerk like you! Especially with the evidence living right here in Central Texas...not left far away in Germany!
My daughter is a good person. So is my grandson. They deserve respect. Too bad that you choose to withhold it.
