I'm a "one and done" guy. I'm not getting remarried. Thankfully GF feels the same way. She has her place, I have mine. It's nice that whenever we want to retreat and have some alone time we can do that. We've been together coming up on two years and neither one of us feels the need to get married again. Her daughter gets whatever my GF leaves to her and there's zero question about it. I've already told both my sons they're on their own as I'm spending everything I've made and leaving them with the same thing my parents left me: nothing.
I worked for everything I have (twice now ...) and they can do the same.
