My mother died 10 years ago, since then my father tried to get married several times but his mother was against it. Then she died too, so my dad’s dream came true.

A few days ago his sister called me and said that my dad was going to get married with a woman who had three children and they all would live in one house with me and my dad.

I was shocked. I said my dad he had to chose, either me or his future wife.
He said that I couldn’t change anything. I was shocked, because I couldn’t live with that woman and her children so I rented a house for me and started to live alone. But that woman and her children live in my house with my dad.
