He wants to break up with me because i don't want to have children

It's a big life issue that can be a deal breaker. It's better you know now rather than later so you can both go your separate ways and get on with your lives.

I broke up with someone for the same reason.

I'm worried this will happen to me. I have zero interest in children and I hope I won't be forced into a bad situation because of that. I'm sorry this happened to you and I hope things work out.

Sounds like he changed his mind, and he has a right to change his mind. If he's actively trying to get you to change your mind or didn't take you seriously then that's really shitty of him. Four years may seem like a long time, but it's hella shorter than ten years. At least you're done with each other.

I understand his point of view, someday I want a big family of my own. And it's a huge issue that those who want want children shouldn't have to settle without them. However that being said I do agree that it was wrong of him to not acknowledge what you said on the matter earlier on in your relationship. It seems like he was hopping to slowly bully you into changing your mind and that is completely wrong,

Psh. Why in the world would a man care to have children now? Being childless is great, especially getting a full night's rest. It cost $300,000 to raise a child from birth to adulthood. I would give him reasons and what to look forward to if he plans on having children.

It's normal to get into a relationship with certain ideas and expectations, but they almost always change. Sometimes it's too one-sided to be sustained. At least you found out how he feels before you got married or he sabbotages your birth control.

Why would anyone care about future generations?

Some people can't think for themselves and the genetic urge to spread DNA overpowers what should be rational thought. There are over half a billion orphans on this planet. Children who will starve to death or die of exposure if not cared for, and selfish ass Americans and "westerners" have 3 and 4 kid households sucking off the govts tit. Plus... If I was a woman I wouldn't wanna push a human being out of my cooch after carrying it around for 9 months. More people should adopt from foreign countries and stuff. Who cares if your child is black or chinese. They'll love you just as much as your own flesh and blood and you will too.

I often fear this will happen to me. I hate kids and don't ever want them. A guy wanting kids is a big deal-breaker for me.

For such a serious subject, I'm a little surprised it's only come up twice in a 4 year relationship. Your boyfriend was certainly presumptuous in thinking you were joking about such a thing, but it's also possible you hadn't been clear enough about. I don't know either of you at all to be sure. I don't think there's much you can do to prevent the breakup aside from conceding to have children, but I hope that you don't. A breakup over this thing is certainly not unusual, though I'm sure with how long the relationship has been it will be far rougher than if had been addressed properly the first time. My condolences to you both.

He probably didn't know what he wanted before, but i'm glad you told him way before hand so it's not your fault. Father nature is calling on him now. It's sad, but you guys need to break up, because this is something that will cause problems in the long run. A part of him will always want kids, while a part of you will not want to. Just don't think your relationship was build up to nothing. I feel like this a end to your relationship, sad. maybe adoption? I don't know

If you can't agree on whether or not to have kids, that's a pretty huge deal. It's not something that can ever be compromised on by either side.

Better that you break up now than after you get married and things are even more complicated.

To be honest, I would do the same. I would never want to be with someone who doesn't want kids; as mean as it sounds.
It's completely normal that peoples' minds can change.
It's better that you two part ways because you have very different interests.

Hey, people change. Now he wants children and staying with you wont give him any. At least he is being honest with you. Men have biological clocks too. It's better to split now than to have huge regrets later when you can't do anything about it. Now you both can move on.
