I've been with my partner for 10 years. I had come out of a long term relationship with a baby, and made it clear my next relationship I wanted engagement within 5 years. Partner agreed at the time and said marriage is what he wanted. Fast forward to now, he's saying marriage is pointless nowadays, and won't benefit him. He's saying I'll sponge him for everything he's got (I'm the main earner). So I'm not sure why he's suddenly changed his mind. We had a major argument over it the other night, I usually gently bring up the subject once or twice a year, because I want to know where I stand. He shouted saying all I do is nag him about it, despite not having mentioned it since early last year. So my only option is to leave or suck it up as it's clear it'll never happen. I know the benefits of marriage as I saw my mother lose everything after her long term relationship broke down. I just want to know whether I can still have the same level of security without marriage. Because clearly I'll never get it with this current man. We have a young baby and I don't share any other assets with him (home, savings account etc). I did an informal proposal a few years back, which it was a straight no, so I've tried.
