I haven't read the full thread and I'm only going to comment once. Sorry it's long. Sorry if it's inappropriate.
In my twenties I was in a relationship (looking back it was so obviously problematic) with the father of my first child. My second pregnancy was an unwelcome surprise. My partner instantly turned nasty, cold, aloof and told me in no uncertain terms that he not only had decided he didn't want another child, but he definitely did not want one with me (nasty shock) and I should seek a termination.
It was a cruel blow. I come from a religious background and found that hard to get past mentally, but aside from that, I kept looking at my first child and thinking that this child could have been her. I knew the reality of what a pregnancy was.
Weeks then months went past. As he continued to insist I have an abortion and time was running out, he became increasingly verbally cruel, I felt more and more low. I fell into a depression. I couldn't stop crying. I hated being pregnant which was causing me stress, but at the same time I couldn't bring myself to do it, and I begged and begged him to change his mind. At one point I even got on my knees in front of him, I kid you not, and his response was to coldly push me aside and storm out.
He refused and told me he would piss off abroad and I would never see him again if I went through with it. He used threats and at one point even cried like a child in front of me and accused me of ruining his life and pleaded with me to 'think of the costs, think about wanting more in life'. The very worse tactics were when he would switch and pretend to be all caring, be good partner, buy presents and hug me and then try and 'reason' me to do it.
But I knew I would have to carry the mental burden, and I would have to live with the consequences. Either way, whether I continued with the pregnancy or not, he was always freer than I was and could always leave anyway. And I knew I would hate myself if I went through with it and he pissed off anyway. I knew men are strange they will tell you to do it, then despise you afterwards anyway, as later happened to an acquaintance of mine.
I somehow got the strength to go through with it despite everything and his emotional cruelty (and that's what it is) when I gave birth, he point blank refused to attend the hospital. Didn't see our daughter except once briefly where he acted like a cold bastard.
And you know what? After all that horror and drama and making my pregnancy a living hell he eventually came round. It took six months before he held her properly.
He is today a great father to our daughter, a girl in her early twenties. You could not ever believe he was so nasty and cruel. He was the dad cheering ridiculously loudly and proudly when she graduated with a degree in Architecture a few weeks ago.
Let me tell you the end of this which is purely unique to me:
Two years after giving birth I went on to develop a severe previously undiagnosed autoimmune disease and never got pregnant again. I am now thankful I had both my children when I did, because I couldn't have had them later.
My ex is also now infertile, I don't want to go into too much detail as possibly outing.
My point is: YOU are the one who has to bear the burden of any choice. Frankly, I feel a man has no right either way to tell a woman what to do with her pregnancy and certainly not put pressure on her. A man has ZERO idea of how many different hormones and, chemical responses are going on in your body and we now know that we retain a teeny microscopically small bit of our babies dna in our brains. A man can't possibly know EVER what it would cost you either way. If you want your babies stand firm no matter what he says.
If you decide to terminate please only do so if YOU want it for YOU and your own purposes. Then you will be able to look back and feel ok with the decision.
Of course it doesn't always work out this way:.
A friend of a friend had 3 boys and terminated her pregnancy after her husband put pressure on her, telling her it was about finances, they couldn't afford another child and they had no family support as they had emigrated from Poland, well he left anyway and within a year got another woman pregnant and moved in with her and their daughter. So it was about HIM, not the situation. She was pretty pragmatic about it anyway, but said she probably wouldn't have done it without the pressure he exerted on her. He's turned out to be a shite father overall hardly has any contact with his kids, hence her pragmatism, but she does feel she didn't have full agency in the decision and that part of it bothers her even decades later. She hates her ex now. She cannot even speak to him.
So do what YOU want. Either way. Make sure it's not for a guy, because a) they can disappear anyway despite telling you it's FOR the relationship, money etc and b) they can change their minds.
