I[28M] have been married to my wife [28f] for 2 years. We do not have kids and we do not plan to. I have a little sister [11f]. Due to the age gap, I am more like another father than a brother.
My father passed away from pancreatic cancer. There are 2 options for my sister: either I take her in or my uncle [dad’s brother]. So we asked her who she wanted and she chose me.
Here is the problem, my wife and I decided that we did not want kids, So she does not want to adopt my sister especially since my uncle can. But my sister has no parents now and I want to make sure she is able to recover and be healthy and since she wants to be with me, I will not force her to be with our uncle.
This is causing a lot of tension with my wife, things escalated and finally I told her I am doing this whether she agrees or not, she can either accept it or we get divorced. We have not talked since then. What can I do in such a situation?
