Yes, you too, are in the army if you choose to marry a man who is in the army, it's part of the package. And of course a divorce is NOT in order, you have a baby for goodness sake! Stop being right about everything.
You can not change him but I do know, as soon as you start changing yourself, you will see him change! If you just do little changes, you will see a change. How's your tone of voice to him, do you call him sweetie or hunny or are you always barking orders to him? Suttle changes like this can go a LONG ways! And yes, men like compliments too!
We have a baby and we help each other out. If my husband wants me to make a bottle for the baby I am happy to because my baby is the one that needs it. We don't keep score and know who did what last, we just help each other out when we need it. It's quite simple!
You need to show respect, before you will receive it and honestly, it doesn't sound like you are being very respectful of him. You sound like you are young and still somewhat immature. I don't mean that to be rude, but maybe you just don't understand yet how relationships work. If your baby is the one who benefits, then who cares who's turn it is to make a bottle or change a diaper, it's for the baby.
Also, it takes two, to fight over dumb things, so that means you are taking part also, in the fighting over dumb things. Accept your responsibility in this and don't just blame him. Change yourself, first
And about the burping and farting...it's a man thing, sorry. They all do it! Maybe if you laugh at it, he will stop. Perhaps he's doing it because he see's it gets a rise out of you. Try burping and farting back at him and maybe he'll stop! :)
Good luck to you, and please try your part in changing. Do it for your babies sake! It never is just one persons fault.
