I 19 years old, and my period is 49 years old. She doesn't have a good relationship with my uncle and has let her relatives beat him many times. My uncle was seriously ill and passed away.

No, although you like each other and can't control your feelings, calm down and think about it. She is your great aunt, and you said that she has a bad relationship with your uncle. She let her relatives beat your uncle many times, and all of them were killed. Such a woman is horrible. You like her now. What if one day you change your mind? What will she look like? Have you thought about this? Besides, you are sorry for your uncle by choosing to be with her now. Think about it!
