Too much for whom? You? It wouldn't be too much for me.
It's not your choice. And you've no right to try to emotionally manipulate the OP in what is already a very difficult time for her.
She already has 3 children who have no contact with their father.
As a couple, they already have 5 children.
Neither of them want anymore.
She is likely to end up as a single.parent to 5 children if she goes ahead. She might end up.as a single parent to 3 regardless. And 7 if they stay together
That would be 5/7 children to house and transport and clothe and provide for. 5/7 children whose needs must be met.
It's easy for you to sit behind your computer screen telling her that children grow up in the blink of an eye. They don't. I have 2. Yes, we all get to their 18th birthday and wonder if we could have done more, read more stories, played more games, been more present, if we worked too hard, if they know they're loved, if they had enough. And it all feels.like it happened so quickly.
But those 18+ years are long and they need time, money and emotional resources because they don't actually wake up one day at 18 (or even 4). It's a lot of hard work to get there. And tugging at heart strings when it has no impact on you is cruel.
And there is no way that any single parent can provide for 5 children as well as 3 woth no support.
And maybe my position would be different if these twins would be her only children or if it wasn't twins. Or if her husband was coming round to the idea. But none of those scenarios are hers.
