My partner and I have always had our own savings. This was why I didn’t want to get married when we were about to have children as I had savings. I wanted to keep them just in case things didn’t work out.
We have now had a civil partnership (once they became legal for heterosexual couples.) We still have kept our own savings but I have money in an online account that he doesn’t know about.
I have never wanted to be blindsided if he left me and our children and find that I had no money. We are happy now but reading on her so many men seem to leave their wives.
