So partner and I together 10 years 2 kids and a mortgage, Mortgage is in partners name as I don’t work and it was easier this way, 
I’m the stay at home parent, 
So recently there’s been trust issues and during the argument I suggested we get married so I’ll legally own half the house, I didn’t think this was a big deal as I’ve always been clear that I don’t want to get married or have the big fuss of a day I don’t see the point to me it’s just a legal document does not change anything in the relationship,this led to a bigger argument of me supposedly being ridiculous so am I the asshole?
