I think for a lot of men having kids is just the accepted default and there's no thought beyond that. Its easier for them because they dont have to grow the thing, generally don't do the lions share of the parenting and as a result rarely have to give up their career.
One friend has always adamantly been no kids and her now husband wanted them. He changed his mind because he loves her.
My husband wanted kids but it didn't happen naturally. When I told him I didn't want to do treatment and just wanted to enjoy my amazing life there was an element of grief for him but he's got over it.
I suppose what I'm trying to say is, dont close yourself off to men who "want" kids. Yes tell them your position, but I dont think its always a deal breaker
I was Internet dating for a few years in my late 30s, about 10 years ago now.
I had originally been adamant that I only wanted to meet a man who had no children. I was open-ish to the possibility of having some but ideally wanted someone who didn't want any.
I realised quite quickly that available men of my age locally, without kids, were quite rare so I did open myself up to the idea of guys with kids and dated a few guys who I was attracted to. However, I was still really hoping to meet someone childfree.
Anyway, after a couple of years of online dating (that I can only describe as 'a learning experience'
) I met my now husband. He had two kids, aged 11 and almost 9. They lived with their mum in a different city and he had them alternate weekends and during holidays. He'd split from his ex when they were toddlers and although his relationship with his ex was tricky, the kids were happy he'd met someone and we got on well.
They were old enough to have fun with and they've now grown into fantastic young adults. I never attempted to parent them but have always been there for them.
My husband was clear from the start that he did not want any more children and I was happy with that.
The whole thing was moot anyway as I fell in love with their dad and I was happy to accommodate the presence of the children. Last year we got married and I'm now officially a stepmum to two adults.
I think it might have been more difficult for us had the kids been a lot younger, if they had lived closer, if he had wanted more kids with me and if the ex was more recent.
Anyway, I agree with above about being open to possibilities. Don't close yourself off to guys who already have kids as there may very well be someone perfect out there with a situation that could work for you.
