I feel like i cant cope and because he is the main breadwinner i cant say much
This is really wrong. When women becomes mothers and decide to stay at home, that does not or should not mean that he gets to have a final say over everything. To live in this situation is to live in a 1950s marriage. Do you want to be infantilised in that way? Do you want to ask him permission before you do everything, like getting the approval of a father? It's an unhealthy power dynamic and needs to stop now before it develops further.
YOU are the one who is mainly taking care of the children, not him. It is YOUR body that gave birth, YOUR body that is exhausted and tired after feeding.
If money isn't an issue then he's being self-centred and unempathic here. He's not thinking or doesn't care about how this affects you at all, and is already exercising his power over the purse strings by denying you something which is quite reasonable.
You have the money - use it. One of the perks of having money and being better off is being able to make these kinds of choices and give you a break.
If he had to wait between carrying on exhausted for 6 weeks, and using the money he's got to give himself a break....do you think he's would think twice about that??
Yes, it's 'only' six weeks.......so if it's 'only' six weeks, why is he not willing to pay for childcare when you have the money?? After all, it's 'only' six weeks, isn't it?
If you want 3 days and he wants none at all, why can't you compromise and agree on half of that? Your child might not like nursery mind - introverted children won't really take to the noise, social buzz and new environment in the same way as a more extroverted child would. I can see valid reasons for not putting her there, but am just pointing all this out because all too often mothers are often made small and vulnerable when they have children because they're financially reliant on their husbands.
