Thanks to all. Much appreciated.
I think the other stuff is biased her way but not all. We don't have a large family so she buys presents for her parents/brother and I take care of mine. Presents for the kids are pretty evenly split as we tend to get different ideas through the year during conversation. She will take care of all the cards though and previously bought all gifts for our friends' kids (not any more as they're all grown up).
I take care of all household bills, sorting out insurances, tax returns, maintenance of the house, DIY but she'll organise most of the social stuff, apart from when we visit my family and friends. She takes care of the garden as I'm useless at that. Yes, she always cleans the bathrooms so I do cherry pick stuff but I'll do some nasty stuff like clearing drains, gutters, plumbing jobs.
Although what I will say is that running my own business is hard work in a different way. She's chosen not to work full-time and I'm happy for her but it places additional pressures on me to make sure I bring enough in and ensure the business keeps on going. Business has been up/down, esp during covid and extremely stressful . I would never, ever let on to her how much pressure I feel as it would make her feel guilty for not working more. But on top of my actual job, I do all the business admin, accounts, marketing, employment etc. I enjoy it but is tough going.
The plus side is it does enable her to holiday with her friends whenever she feels like it and to go away as she pleases (she works at a school so has a lot of time off) on top of our family trips. I feel this downtime may make up, or alleviates, any additional stuff she does that I don't.
For example, it's half term here so she's off to visit a friend for three days. When she gets back she's off again for a spa stay over with some other friends.
We do appreciate each other and make a point of saying it. We both outwardly say were happy too so as far as I know, things are going well but it's just the comment from her friend.
I accept I'm a man and completely blind to some things but I did also wonder if her friend was just stirring it up or being unreasonable.
