My fiancé

And his baby momma have a pretty good relationship they have private conversations while I'm inside "about their son" so I'm told . Me and the father of my child do not speak without arguing. But they are really nice to each other and it kinda irks me is that wrong? Me and her don't get along for various reasons and , to me I feel like she just thinks she's gonna have a bigger place in my husbands life than I ever will and rubs it in or something .
