Myself (f31) and fiance (m33) have been together 12 years, no kids. Within past few years we've both finally got jobs we've been working towards and a nice income. We like our life, being able to go away for a night or two or out for nice meals as we can afford it. Then have quiet evenings watching Netflix. Neither of us want a child enough to actually have one. We talk about it frequently to check we're on the same page. Working well for us.
