tock I'm a bit confused by your DP, but it's a confusion I get with all couples who don't share everything. My DH earns a lot more than me, and spends less than me, but when we got married, everything became ours. His savings became my savings, and mine became his. He brought a lot more to the marriage savings/earnings than I can, but he married me knowing that.
For me, having kids is a lot like being married. He works hard, and earns the money, but you work hard looking after his house and child to enable him to do that. I can't really see how he justifies keeping half his salary as a play thing while you manage all the bills and household finances and live off your savings. It doesn't seem like a fair deal to me.
Surely he can look at his finances, and the amount of money he's spending on his activities, and see how he could perhaps increase his contributions to the family to cover the extra cost of a second child? They're not free, and another child is his responsibility to support. This wasn't an accidental pregnancy for you, and when he gave you his blessing to try for another child (and his sperm!) he agreed to that responsibility. Now he just needs to step up.
There are lots of couples with lots of different ways of handling money, and I try really hard not to judge people on the way they choose to handle these things. Ignore me if I've stepped over a line.
My uncle and aunt used to have a relationship similar to yours - but one day she decided to go out to work to have some money of her own (and less stress!). She 'charged' him half the child care costs, and stopped ironing his shirts, cooking, cleaning etc etc. Not in a malicious way, just because she was busy at work. It lasted 6 months, then he agreed to pay her a salary of her own for the childcare and housework, money she could live on comfortably and spend as she pleased. It worked really well for them having separate finances, so it can work.
Also, my back isn't really much better, but I'm fairly sure it's a muscular problem. It hurts when standing or walking, but especially when I'm doing things with my right arm - like brushing my teeth or holding my umbrella. Today it helped to put my right foot up on the bath while brushing my teeth - somehow offset the stretch and eased the pain. I think I just need a physio.
Fluff the cardie looks really nice, but I wouldn't have a hope in hell of changing a pattern :) I've been stuck for months on the jumper I'm knitting. I've somehow reversed the pattern (doing the same row twice maybe) so the front side is showing the backside. I can't for the life of me fix it! I've unpicked and carefully re-knit it 3 times now and it keeps being wrong. It's the line right across the front of the jumper, just below the neck, so important to get right. I think I'm going to need DH's Nan to help.
cakes that's a lovely neat bump, and doesn't look huge at all. I know what you mean though, mine looks huge to me, but I doubt it's noticeable to others (I've got a photo in my profile from a couple weeks ago).
