My husband has one of those expensive hobbies (LTB immediately, I know) which takes him off for nearly a whole day at a weekend if he wants wants to fully embrace it. I encourage it because what's good for him is good for us and he is wholely supportive of me getting some hobby to do (I don't have any, can't think of any, my hobby is spending time as a family).
As a SAHM to a 4 & 1 year old (who don't go to nursery) and with a husband who works full time 9-5, I actually dread these weekends because it cuts into our family time massively and it's more of me doing the same thing I do every day of the week (clue: being run ragged). I was supportive of him taking up the hobby because I love him basically. But my teeth are hurtin from gritting them as I say 'oh this weekend? Yeah no problem' and acting breezy. I have told him how I feel and he is considerate aka doesn't go every single weekend & gives me plenty of notice and we do things as a family the rest of the weekend.
I just don't like it!
