Don't leave me Babyboy

Part one ( Put Swim on lol )

Jimin POV
When I was only 12 my parents divorced. I moved in with my mother because my Mother said my dad committed suicide. For my whole life my mother watched over me. Even though she was always working , she would come home with cake and we would eat it together on the couch. And when she didn't have work, we would go out together and spend time together. I love my mother so much, I appreciate all she has done for me. When I turned 16 everything changed. My mother would come home the next day when she went to work and when she was off, she said she was going out with someone. I didn't know what she was talking about til one day she came home with a guy. He was tall and dressed nicely. He seemed older than my mother. He was holding my mother the waist, she was drunk. The tall man told me his name was Troy Jeon and to call him Mr.Jeon. He told me he has been going with my Mother since last year. Why didn't she tell me? Once he put her to bed we talked. He seemed like a nice guy, he talked nicely. I liked him. After a while he left. Weeks later he would come over often. It was really nice to have a father figure in our home. But two days after my 18th birthday he announced he was marrying my mother and that he was going to move in with his son! I never met his son, I haven't even met his family yet he's moving in. I'm so confused, we don't have enough room for two people to move in. What am I going to do?
