Here are a few thoughts.
Co-parenting is different than fixing your marraige. you USED to know how to parent together, but the ball game has changed now that you have been seperated for 8 months. Its something new you guys are going to need to learn. Relax if you think you two will get back together. There are probably some things she thought she would do differently when you two were together but didnt because she let you handle some things and she handled other things (picked her battles) but now that she is parenting without worring about letting you handle things, she is showing her TRUE parenting style.
And secondly, I think that more than likely you couldnt sleep because someone was in your bed. Thats happend to me. I'm in the army and there are times when I am gone, but when I come home after being gone for so long its weird to have this man in my bed next to me. Everytime he moves or breaths loud, snores, or rolls I wake up or cant sleep. And hes not just some man, this is my husband that I love.
Being seperated is difficult because there is the you in a relationship (married) and the you that isnt. The you that you were before you were married starts to come back out and you seem like a different person. Even if your not dating someone else. I remember my husband saying I was a totally different person because I started carrying a purse. I told him its not that I'm all that different, but when he was around I would ask him to hold my smokes or phone or carmex for me if my outfit didnt have pockets. When hes gone I have to do it on my own, hence the purse. But to him switching from a wallet to a purse felt like a big thing, a prime example of how I had changed.
So, Mr Making it work, I hope it works for you. But remember not to sweat the small stuff and think too much (like you said) because the changes may seem big now, but they are just small things.
Good luck.
First date night in 8months
I hope things work out for you.
