I'm hoping for a male point of view on this too.
When you start dating a woman who is a stay at home mum and learn she has very young children (eg age 4 and under), right from the off, surely it must cross your mind, if this relationship develops and you move in together, as the working man, you are going to take on the lion's share of financial responsibility, because she will lose many benefits if she moves in an employed partner.
Yes, she may return to work again once the youngest starts school, but until then, it's a big financial burden on the man, surely, enough to put him off moving in thus developing the relationship?
After time of course when in love this will not be an issue, but I am wondering right at the start when you're a few dates in, does it cross your mind it could all be a bit costly? :(
