Well I would call myself a feminist but I will join the noodle and sieglinde and say that my marriage to dh is completely equal and that this is possible.
DH has from the beginning done his fair share of the home stuff. He does a lot of our home paperwork/he admin, plans and does the food shopping, and 60% of the cooking. Makes drs and dental appointments for ds. Deals with all that school paperwork stuff that comes home everyday, sets up playdates and organises and takes ds to activities. He doesn't do it all but he does at least half of all that. He also does housework when it is needed not just when I tell him.
He takes days off work for ds related things when he needs to. When he is away he is the one to stock up the fridge/freezer as he know I dislike food planning and cooking so much.
I did look after ds for the first year and didn't work but this in no way meant that I carried on doing everyting for ds after going back to work . DH shared a lot when I was home and when I went back to work we went back to the 50:50 split on home stuff that had always existed between us; it was just that work relating to ds was now part of that split.
BUT
1 I knew that society being what it is, that having a child was likely to seriously test our "equal partnership. So before we decided to have a child I made it clear that this sharing of roles was expected and nothing less would be tolerated by me. I absolutely would not have married him ( we married when I was pregnant) however much I loved him if I had thought he wouldnt do his share post-children. This really was non negotiable as I has already had one marriage fail due to this problem.
2 Dh has more than lived up to my expectations on this but there is no doubt that his high flying academic career has suffered as a result. My career has also suffered as the result of having a child but as my job meant less to me, it was less of a sacrifice for me. Dh rightly or wrongly hangs a lot of his self-esteem on his job so this has been hard for him.
3 Our lives are less organised and run less smoothly than ones where roles are more divided along gender lines. We have to communicate more as we both need to know if ds needs new shoes, or is due for a dentist appointment (for example) and who is most able to sort it out.
I think therfore that it is possible to have a equal partnership but it is often very very difficult to achieve, especially if it is not seen as an absolute priority by both partners before getting married and/or having children.
I know it sounds very "unromantic" but in my view, romantic love and the ideas associated with it has almost as big a role as patriarchy and capitalism in preventing "equality" in sexual relationships.
