Not a stealth brag before anyone starts.
I have a friend, generally get on well with but she's really money focussed. She did well at uni but for whatever reason this hasn't translated into her career and she's now stuck in what she describes as a "crappy admin job". She's always picked her partner's for their earning potential - seriously, she's dumped guys without degrees or who had manual jobs.
The first thing she told me about her current (long term) partner was his salary. She tells me every time he gets a pay rise or bonus and how much it is. I don't ask for it and nor do I reciprocate the information. She assumes their household income is higher than ours, but it's roughly the same (though earnings split slightly more equally between DH and I).
We have 2 kids of similar ages, primary and preschool. We've chosen to send the kids to private school and since I mentioned this she's done nothing but moan. She keeps moaning about how unfair it is that we can afford private school when she can't. The reality is that we've just prioritised differently - she likes expensive holidays where as we camp, her partner likes a new car every couple of years and currently drives a Mercedes, we drive an old car. I have no issue with how she spends her money, it's the moaning I mind. It's constant - I asked her her plans for half term and she said "well it must be nice to have private school holiday club" and every mention of the kids comes back to how mine are at private school. She's asked how much it is, whether grandparents are paying etc. I've explained that we just spend our money differently to her but she just keeps on about it.
How do I make her stop? I suspect it's partially an issue because her partner doesn't really see their household income as joint - he gets more of a say in what's it spent on where as DH and I make more joint decisions, her partner also doesn't see a need for private school but my friend attended one so wants her kids to have a similar experience. She's realised we aren't as far behind her financially it's really soured things. What do I do? I like the friendship otherwise.
