I can completely appreciate your stance, and also your husbands.
I have 3 children, the eldest is 14 years older than the middle child. I wanted him to have a sibling to grow up with. I really wanted to avoid him being lonely as DD was growing up without a sibling to play with and I wanted him to just have a close bond with someone as I'd long accepted that DD would have her own life to lead.
My then husband wasn't on board. I accepted it. I wasn't particularly pleased but did accept that his feelings were big feelings that would turn into resentment if I continued on with the argument. It wasn't a one wins, and one loses situation.
I told myself, I can resign myself to the loss of that dream and enjoy what I have, and he would be unhappy, and feel resentful, and overwhelmed and like the 3rd child was a detriment to the existing two we had.
Several months later I fell pregnant. It was the earlier days of GLP-1 weight loss jabs, and at the time the warning was if you were sick or had diarrhea you would need to use other birth control than the pill, but there was no warning at the time that the jab itself lowered the effectiveness of the pill given that it worked by slowing down the absorption of food in the stomach.
So I fell pregnant, and from that moment he disengaged with our marriage.
He thought I decided I was going to have a baby anyway regardless of his thoughts. Everything he thought he knew about me was gone in a moment, and he could barely look at me.
And I couldn't believe he thought I would do that to him.
That baby is now 10 months old, generally a happy little boy. He's lovely, he's starting to bond with his brother, the work of bringing them up is unreal, feels like one is always unwell at the moment!
Money, well it comes and goes and moneys a little more stretched, and holiday costs will increase quite largely in a few years time when he has his own seat on a plane.
But the real cost is now I am a single parent. A relationship I'd been in for 14 years, almost 10 of those married, is gone. The family unit I intended to give my babies will never exist. Going back to work is a far off dream.
Their father is involved, and he's sorry for his treatment of me during my pregnancy, but he never wanted a 3rd child and I guess for that I don't get as much support with the kids as I could.
I really want you to be prepared that if a 3rd comes along and he's not on board, it may destroy your marriage and rip the guts out of the life you thought you would give your children.
