Fiancé insisting on donating sperm against my wishes

LTB

At least you don't and won't have to waste much more of your life on him. Also don't try and force a relationship between him and your child if he's not interested. Do get financial support though.
Maybe donors should have to pay towards the kids they create. Would stop people like that idiot who has had sperm used in over 1000 kids created. Awful.
A friend did this with her children and their fathers. With one it was brilliant as he was an involved parent. The other 2 not so much and caused hurt for the children. They did not want to go.

Do you still want to marry this man who has demonstrated a complete lack of concern for your physical and emotional well being and has a weird “legacy” kink.

Imagine if, at some point, your daughter unknowingly falls in love with a half-sibling. How many people have genetic tests before they have children? For her it will be necessary to avoid incest or inbreeding!

Ask your partner if he wants that for the one child (of potentially dozens) he’s decided to take responsibility for. Yuk.

Even if you do leave him, this is going to haunt you and your daughter for the rest of your lives.

I bet he’s suddenly going to become one of those guys who insists on natural insemination only and expect you to go along with it. 🙄 You should have dumped him for the cheating alone. This is extra creepy on top.

So sorry you are experiencing this OP. Look also at the upside, he has shown you who he is and what he values plain and clear, please do not ignore this. You chose to give it a chance after the affair, people make mistakes. His attitude doesn't show gratitude and determination to repair the relationship and rwmorse for his behaviour. He just found other ways to torment you. Many, many women end up in dreadful situations and most of the time they had plenty of signs to not be in that relationship, which they ignored. People don't just change if you give it time, they have to want to change and look at themselves and their contribution to the relationship. A relationship is not 50:50 it has to be 100:100% to be happy and fulfilled. Take care of yourself and your child, who will also be affected by your unhappiness evwn if you might think you are hiding it from him. It is never too late to rebuild and make good choices for your life. Sending you love and wishing you strength and courage x

When one partner wants more children and the other doesn't it's a hard situation but this doesn't sound like the real issue, if it was he would be interested in adopting or fostering or being involved in youth work or something, something that actually involves being involved with and nurturing the children. Not donating sperm.
This sounds more like some kind of game or ego power move he wants to have over you. He's putting that ahead of your relationship, that shows you how on board he is with 'the team' that you are supposed to be.

So he's a selfish, cheating piece of shit who wants to shower the world with his mighty seed.

Sooner you get out the better.

He's manipulating you using this excuse.Get away from him as soon as you're able to.He sounds a really nasty piece of work.

He said he is determined to carry on as it is his life goal to have lots of children and won’t stop this process.

He’s mental. HTH.

Child has your name, right? please say they do.

Leave him. He isn't going to stop, and he has no respect for you.

Please leave.

Sounds like a very strange man / situation…

This is exactly what I was thinking. He could have had more than one affair already, be continuing the affair that you knew about or keen to have more and so likely to produce more children. Donating sperm would be a good cover story for the children who might come out of the woodwork in the future. Sorry op it doesn't sound good at all.

Surely you mean ex fiance now? There are so many things wrong with his behaviour and mentality, I don’t even know where to start.

Sounds like he's got a weird breeding kink. Do not marry this man.

Andrew Tate/Elon Musk wannabe! You know you need to get rid

Are you seriously going to marry this creature??

Blimey, just when you think you've read all the possible iterations of vile, narcissistic behaviour on MN...

Please move on and build a better life for yourself.

What makes his dna so spectacular that he wants to satisfy some primal urge to spread his genes far and wide whilst having nothing to do with the raising of these children?

An affair and now this?? What in the Elon Musk is going on?

You need to leave quickly. Like yesterday. Either he has a weird procreation/breeding kink, or there’s a kid about to be born that he’ll conveniently blame on being a donor.

I’m not one to bash forgiving cheating, I’ve done it and I’m fine with my decision, but this man seems to have a fundamental disregard for you or your family. I’d be thinking he’s a red pill type too.

"Like my opinion doesn’t matter in the slightest…"

Well, it doesn't does it? He doesn't respect you, he doesn't give a damn about your health and he sure as hell doesn't care whether you agree with his plan or not.

Sometimes I find it hard to believe the shit people are willing to put up with.

Why on earth are you still with this hideous man? He sounds utterly vile.

It sounds like a fetish or kink OP. He’s vile and I hope they screen for this strangeness before accepting donations from weirdos

This man is just a wrongun I’m afraid. Only interested in spreading his seed. I think he needs throwing back and he can do what he likes with his seed then.

He is a very strange, odd, weird person. Set your plans in motion and get away from his disgusting misogyny.
