LTR, both in 50's. This has been going on for some time (I would say this stand off is a year or 2 but making me more and more stressed).
It will sound so minor and ridiculous but it is creating such stress and anxiety for me.
My DH likes to have a bath, not a shower. He likes the "soak" and feels like he doesn't get clean properly in a shower (he has job where he can get quite dirty), and also he likes to wet shave in the bath (hates doing it just at a mirror with a sink).
He also has a thing about saving water. So this means that he wants me to have a bath first and then he can get in afterwards.
So as not to drip feed - i guess we have done this a lot for our relationship - early days we had properties that didn't have a shower, and then with small children we would jump in the water after them for convenience. (and he says why do we have to change?)
However I find having a bath time consuming, I often want to shower in the morning not bathe at night, or want to shower when I feel dirty/sweaty (my job can be quite physical). I also think my hair washed much better in shower than rinsing with a jug in the bath.
He has a habit of saying "can we bathe tonight" and gets really arsy if I say I don't want one as I have already showered or like last night it was so hot yesterday I showered not bathed. He was sulking and angry all evening (made it about something else but I know it was about this). He has asked again this morning "can we bathe tonight". I have said it is too hot, and he just goes on about how I can have a cold bath (it's apparently no different to me getting in a lake when i swim???), and that he wants to shave.
We end up in this argument of why can't I just have a bath, it saves water if the two of us share a bath (I actually disagree on this as the 2nd person always puts more water in so I think a one person bath and one person shower would be the same - i have quick showers and we don't have a crazy power shower).
He has even in the past then refused to have a bath himself and had a strip wash instead (making a point that he hates showers).
There is total major guilt trip and such anger from him - i know this is totally weird and out of proportion and I can't live my having this much anxiety over a fucking bath, but equally I can't deal with the fall out when I stand up to him.
He thinks I am being totally unreasonable.
I am going away for work for a few weeks tomorrow, and seriously thinking of sending an email about this to him when I am away so I can clearly lay down boundaries whilst having some space away.
Not sure how else to deal with this in an assertive way without ending up in a major row :(
