I am currently very pleased with my decision not to marry.
We are separating after 20 years of very successful parenting and running a family.
When we got together I earned more (always have) and had far more equity in my little house than he had in his flat, and he had debt.
We bought a house together as tenants in common, with our respective equity protected.
We shared parenting. Equal assumptions about covering sick days, holidays, we each worked 4 days a week during the pregnancy-school years to cut nursery bills and increase parenting time.
We have wills and POA documents.
Now we are selling up and I get my original deposit back ( as does he, but mine is 4x his). I can afford a place as a base for Dc during the Uni years. I have the security for my future that I worked so hard for before we got together.
Had we not bought a house together I would be twice as well off now (one family house does not appreciate like a flat and a house separately, and I wasn’t smart enough to have the shared in the house expressed as a percentage, so he is benefitting from half the increase in value of my deposit), but that’s OK, primarily I wanted a home for Dc and we have done that.
Had we been married the value of the house would be split and neither of us would have had enough for a place that Dc can come back to. My pension (I was much more conscientious before we met, and continued to save... he had employer’s contributions years before I did but never topped up).
Splitting is still painful and cumbersome, but I am so glad we did not marry. I would have gained nothing and lost my security.
