So. DH has a history of giving the kids presents when they finish exams. This is alien to me, definitely not a part of the family or social culture I was raised in, but I understand that it is fairly common at least amongst the kids' schoolmates, etc.
Relevant other points - we argue abut two things: 1, he indulges DSD and I feel that her desires often trump the needs of the other kids or of the family as a whole. 2, he makes major decisions without talking to me as a partner. We have also had some issues over money in the last year, mostly stemming from him not being able to manage money very well, getting into a bind, and then trying to hide it from me because he is ashamed of himself.
DSD just had her GCSEs. I suggested to DH a month or so ago that a new laptop might be a nice gift. She has a laptop but it is an older model (used to be DHs) and has some issues (battery life, etc). I'd seen some ads for good new laptops that were in a price range which, while it would be a stretch to our finances, would not be impossible. He seemed to think this was a great idea. We were both pleased at the thought and at how happy she was going to be.
Then the time gets closer, and he tells me that he's intending to spend £1000 to get her a really top of the line laptop. While we have some income, we both work part-time and are students part-time (both working on our PhDs), and mostly we live off savings at the moment, and we don't have a lot of financial stability. My engagement ring cost about £150, and I bought a dress on bay for £10. I haven't had new clothes since before I was pregnant - my maternity clothes were passed on from my sister. We bought a laptop for me when I was pregnant, for about £300. The baby wears clothes that were presents or her male cousin's handmedowns. I bought her a used (and kinda shabby) pram for £6. We don't go out, because we can't really afford a babysitter. Point being - we don't have a lot of money to spread around in the first place. and while I'd like the kids to have nice things, I think £1000 on a laptop for a teenager is a bit OTT.
So, we argued about the laptop. He agreed to look for one for about £500. He found one, too. Great. She's very happy, although I think that the upshot in his mind is that I prevented him from getting her that really amazing £1000 laptop, and the fact that it was my suggestion in the first place is totally forgotten; instead I'm just mean.
Then he tells me today that he also bought two other laptops at £300 each, which he plans to resell and try to make a profit on. So, he spent the £1000 anyway, and didn't consult me about it. I'm livid. Seething, really.
AIBU?
