Avenging and Bathtub OK, turn it around, if OP was wanting to have a hobby and DH was miserable and posting about it, would you be all saying the same?
It's all about taking a longer view, whenever any DH leaves the toilet seat up, it's the same old names shrieking Stone Him, Stone Him!
If a DH has to be kept on a leash, when it's finally let go, he'll just keep running. Likewise a DW, it's about trust and letting people explore themselves and have fun.
IMO OP seems frustrated, jeez who isn't, but my time will come, I'll get my time off, breaks, things for me to do, in time. And I dare say she is a lot younger than I am..
Life IS all about give and take. Our foremothers had better percentage chances of a sucessful marriage than is available to our generation. Why? because of tolerance and putting up with stuff SHORT TERM for the greater good.
It all evens out. We're not talking about abuse here, we're not talking cruelty, we are talking about a man working hard and playing hard.
OP could make an effort initially, to see if it's viable to go to, take DC to etc, some meets won't be, but some will.
It won't hurt to try and look at things differently, it may even help, OP may even have fun sharing in a new family hobby... You never know unless you try.
I'm not saying give in to everything, all I'm saying is take a wider view, have a try and see. The statistics tell me that to take a radical unforgiving and ranting view is painful for all parties and achieves nothing.
Also, there's more than one way of skinning a cat...
If OP goes to a few meets then, with proper knowledge of meets and experience, she can have an informed chat with DH and negotitate the time he spends doing this to a more manageable level.
Going in all guns blazing from the start will just make him dig his feet in, and be more determined to do it. Then OP will have a devil's own job to get him to limit it.
If you are clever, and plan your moves, you can get people to do what you would prefer them to do, but they think it's their choice.
