I have name changed for this. I was married and divorced in around 2012. The divorce cleaned me out - exh behaved like an arsehole. Spent all his money and then lost his job so claimed he had absolutely nothing and I ended up having to remortgage the house I had already paid for.
I've been super cautious since then and have never thought I would consider being married again. Dp (been seeing him since early 2018) moved in in July 2019. I didn't think marriage would be on his mind either but he dropped a hint about it over Xmas which made me think he is thinking about it.
But I come into this relationship with way more assets and fewer dependants (he has 4, I have 2 and importantly one of mine might need life long support as he has SN).
I'm happy to share what we build together but I would like to ring fence what I had when we got together. Is that legally possible in the UK? (I'm not saying I would even say yes to a proposal but just thinking through the options!).
