I am a bit of a lady of leisure at the moment with one school-aged child and only working running an extremely small and fun business from home which doesn't require a lot of work at the moment. I cook us all breakfasts, do the school run, do a fair whack of the housework (because I can during the day with DP at work and DS at school). I cook dinner and DP does the dishes and cleans the kitchen after. I do laundry.
When I worked fulltime housework was a little bit more evenly spread but me still doing the lion's share. To be fair DP never cleaned when he lived alone but does so now purely so I'm not doing it all.
what makes the biggest difference for me as opposed to being with my son's biological father is parenting is very much shared. He comes to parent-teacher interviews, sports days, plays with him after school and helps with his homework. With my ex I felt very trapped because I could never go anywhere without a child tagging along which meant I missed out on a lot of things I enjoye and lost a lot of great friendships. There was a lot of resentment on my behalf. Now I go to my yoga classes twice a week and DP cooks dinner for DS and tucks him into bed and if my friends invite me out and it's something not suitable for children the only thing i have to check is whether DP had anything arranged, if not off I go!
