Mum problems

Kimberley
So if this turns out to be a long post. 
So to give you background info me and my fiancé have been together for 2 years and close for 9 years. We are getting married in October but are currently living with my parents (which we pay rent and pay for our own stuff)  this suits us for the time being as we really wanted to get married but knew we couldn't afford to do it once we had our own place so we've decided to do it before being married and then get our first home together as a married couple. 
I wouldn't say we had a traditional relationship as it wasn't put out there by my fiancé that he wanted me to act a certain way but to a certain extent I would say it's closer to traditional than modern relationships these days. He works his arse off Monday to Friday whilst I'm off work sick at the moment as I've just been diagnosed with bipolar and major anxiety and I'm having therapy (I still manage to pay all my own bills.) 
I make my fiancé's lunch in the morning, iron his clothes, put them in the wash, get him clothes out to get changed after work, cook his dinner and will run him a bath. To me this is just natural and I love doing it, my fiancé is always grateful and never takes it for granted. I love having our relationship like this and it keeps me busy during the day which is need without too much stress.
 My mother on the other hand sees this as me being a mug and that I'm allowing myself to be used which is not the case at all. Her relationship with my dad is that whatever she says goes and that the woman is always right and that the man should agree. I hate that as I believe it should be equal on all parts. It just angers me so much that my mum will drop sly comments all day about what I do for my fiancé. 
Has anyone else had to deal with this?
