Ok... so Be my best... I can be a great dad. Easy. I'm all over that lately. But what does be my best mean around her? Do I do nice things for her I would normally do. I stopped doing those things recently when she moved to the basement.
What if she asks to come back in our bed?
I don't want to screw this up and push her away.
For the few weeks after BD but before we were separated, I was EVERYTHING my XW had asked me to be. I was a great parent, I listened and talked to her about her career, I bent over backwards for her. I tried to prove to HER that I was good enough. Of course, that was wasted energy.
My point was that you should just be the best version of you that you can. There's no reason to try to SHOW it to her. If she's looking, she will see it.
