I am currentley engaged and we are suppose to get married in January. Every time we fight it gets bad verbally we say its over and things like that. This last fight is because I said we don't need to spend as much on his son than my kids because he is hardley ever with us. Now we are fighting but I didn't mean any harm. He is now saying he supports my kids and its not his fault their father is a **** up and don't provide for them. And the house is not my kids it's his kid. Any advice

Well you should tell him you meant no harm with the comment you made communication is the key and I'm sorry but he doesn't need to be so cruel about your kids not having there dad it's not there fault!
