There has been a change for us too. I was a sahm with small kids for a time and i think wh took for granted everything i did around the home with small kids in tow!
I tolerate a lot less these days in all aspects of our relationship and he will not take for granted what i do at home again.
Our kids are older now and are all at school. I work part time (4.5 hours a week over 3 days, very part time ) so i do take on the lions share of housework, which is fine, but he helps out a lot more at home than he used too.
