I know I KNOW this has been hammered about the woman always wanting to keep the baby but the guy doesn't and shouldn't be financially responsible blah blah blah but hear me out. What if say you're in a serious relationship, you're both in your 20's and have jobs, house all that jazz and, you DO practice safe sex but an accident happened. Now, the woman would like to be married and have a career before a baby...this just isn't the right time but the man is so excited about possibly having a baby now. I don't know what to do...I didn't really know what to put as choices. sorry if they suck.

Talk it over with him and if he makes it clear that your relationship will end if you get the abortion then you're going to have to sort your priorities out. It's his wishes and the relationship over your own wishes. So what's more important to you?
You're the one that has to carry the child for nine months. If you are willing to do that but you don't want a child then hand it over to him. He can take sole custody and you can have visitation. If he's not willing to do that in order to keep his child then there's no use in going through with the pregnancy without some legal assurance that you won't end up single with a baby on your hip because he thought he wanted to be a Daddy but then he couldn't handle it or you. You can do all of this before the baby is born.
If you two have a very trusting relationship then you can marry him and have a family with him under the premise that the childcare is mainly his responsibility.
But if you just can't have a baby right now and he can't accept that then you guys may have to break it off. I'm all for men's rights but not when it comes to this. Carrying a baby for nine months and giving birth followed by the recovery process isn't a joke or something to be discussed hypothetically. A pregnancy changes your life and body regardless of where the baby goes afterwards and until men can know what it's like to carry a child then they don't get the right to force pregnancy on a woman.
"It's her body, so it's 100% her choice!" Is something people agree with 9No doubt mostly women)
But "It's her body, so it's 100% her responsibilty" is something that should never be said. Pfft.
If women get full choice of having a child because it's "her body", then she should have full responsibility of it due to it being "her body".
But watch, look at the thumbs downs I get, yet watch nobody come with any good reasons to say I'm wrong.
