I was in this situation and went ahead with the baby as I was not prepared to end what was essentially a good relationship even when I thought that, regardless of how much my husband wanted a baby, he wasn’t grasping the idea of the level of responsibility and sacrifice involved in raising a child.
That baby is the love of my life, as another person here, I have loved him dearly since I saw him at the first scan. I wouldn’t change him for anything, he comes first, I have sacrificed a lot of stuff gladly to ensure he is well and happy, but…
I have been raising him singlehandedly for most of his life as his dad never properly transitioned from married guy with a single guy freedom to responsible parent, so soon enough the responsibility to raise and care for DS fell gradually but firmly on my hands, this lack of balance eventually caused us to split.
Not much later, once he had set up with a new woman who resented DS (and hated my guts) he emailed to say that given the circumstances he felt forced to take the option to stop contact with his son.
And I think that is the crux of the matter, for many men a child is an option, caring for them is an “option”, staying in their life is an “option” as well, even paying child maintenance us often perceived as being optional, but a mum will love a child so much (blame the hormones if you wish) any “options” will be always chosen in consideration of the child’s needs.
So OP, I don’t think I am lying by saying that when it comes to children, the only truly personal and free option women have is to have children or not.
