Your husband being a fantastic father to two doesn't necessarily mean he will easily and naturally progress to being a fantastic father of three. He may be a great dad to two because there are only two and that is, in his opinion, emotionally and financially his limit
This ^^ I have 2 lovely children, but I don't want anymore. And nobody would be able to force me into it. I am the parent I want to be to my children, I wouldn't be able to say that if I have a third.
All those who think her dh is being unfair, I wonder if you have ever thought what the impact of being an unwanted child means. My mum wanted to terminate when she was pregnant with me. I was her fourth, she didn't 4. She wanted 2. She had #3 under reservations, but went on to love & cherish her as much as did her sons. She wasn't allowed to terminate me, she was told by her brothers & my dad that all would be OK, it was with #3, look how well that turned out. Etc. So she continued with the pregnancy. And here I am, 40 years later, suffering from the legacy of being an unwanted child.
Because it didn't work out. She didn't love me how she loved my siblings. She couldn't hide it either, and I am left wondering how on earth people even like me, let alone love me, because my own mother couldn't! Struggling to understand how a mother could reject her child like that. Struggling to understand why I am the only child she doesn't talk (haven't spoken for 20yrs). Struggling to understand how she let me leave the country we both lived in, with not so much as a word when she saw me in the street days before I emigrated.
She didn't tell any one that she threw herself down the stairs, or drank a bottle of gin & had a hot bath (old wives tale) to try to self inflict a miscarriage until she told her boyfriend at the time, while in the same room as me. And living with that is indescribable. Knowing your parent didn't want you, wanted you gone so badly, that she inflicted that on herself.
Add insult to injury, when I was still a little girl, my dad left. So there I was, being raised by someone who didn't want me. And yes, I blame my dad too. So how do I reconcile that? One didn't want me, one left me.
Does a lot for your self esteem, that!
