I rarely do the dishes, my ISFJ mum and ISTJ dad do them, about 40:60 (my mum's got arthritis so the ratio's altered a little).
My mum's the one who ends up slaving away mostly regarding housework (cooking, cleaning, tidying etc), even doing it after she's asked me to, I'm forgetful and lazy, my dad's dutiful with a bad sense of when is a good time to get agressive about it, and I end up getting annoyed and associating housework with feeling angry. So I don't think that side of life will ever be a problem for me.
I'm not sure otherwise. I wouldn't say I get taken advantage of. I would say I've got a slight tendancy towards codependant relationships with males, but I avoid that.
As for being generally accomodating and too nice...I'm not sure. I'd call myself conflict avoidant more than accomodating. Too nice? I want people to like me - and I enjoy harmonious discourse - so if it comes to a choice between being very reserved and awkward, and friendly I'll choose the latter option as it's been the less stressful one generally. I don't know about being 'too nice'...I don't like making others feel bad, and I get overwhelmed if they get angry. I don't see the point in persuing conflict where it won't lead to better things, and I'm scared of it most of the rest of the time.
I would call it cowardice more than some kind of martyr syndrome.
