I inherited my Aunt

My parents died in a plane crash when I was 16 2018, I was away a school so wasn't with them. So, I was left with my father's older brother, who only child had died on active service when 22 in 2017. His son was from his first marriage, and his wife had died of cancer in 2010. He remarried in 2016; his new wife was 22 at the time of their wedding. She is quiet, timid and was more of a servant than a wife, rarely spoke when my uncle was nearby. He got cancer himself in 2019, had ignored the signs for years. Testicular cancer and had he had it treated early he might've fathered another child. Lost both his testicles to the cancer and it had already spread thru his body as well. He finally died in 2023, and I inherited everything from him. His wife was also left into my care, no money or anything else left to support her just left to me to care for. I was at the time a quiet person, mainly because my uncle was a loud person who always wanted to be the center of attention. But with passing of my uncle, I came out of my shell you could say. My aunt could've contested the will and won I believe but she didn't want too. We had always got on very well and she trusted me to care for her. I like camping and trekking my aunt started to accompany me; we didn't need to work due my inheritance from my parents and that of my uncle. During one trekking trip in 2024, it started raining minor at first than heavier. Unable to travel for 2 days, together in a small two-person tent. One thing led to another and now we've a daughter, my aunt loves being a mother and doesn't want me to marry her saying I should find someone closer to my own age. But still sleeps with me every night, she has also come out of her shell not as much as me yet, but she is still emerging. I've asked her to have another child for me, she has agreed. Sex is always unprotected. We've the same surname, so no real need to marry. I do date but nothing serious at the moment, because I've my aunt to satisfy my every need.
