Is it normal to feel this way?
I've been living with my step-sister for about 3yrs now. We don't really get along but we try to. And I know that alot of the time we are fighting. But there is one thing that bothers me. Since I met her she has had about two boyfriends but it never bothered me. There was this boy in my class that I noticed and thought was really kool. He plays drums and I love listening when he does. I used to try to think of something to say but I'm really shy so I let it go. About a week into summer vacation I found out that my step-sister just started dating him. When I first found out it was like my whole world just started crashing. When I see her texting or talking about him it hurts. I've noticed that we have alot in common and they are as different as night and day. At night when I think about him with her I want to cry. It irritates me and I'm forever trying to get her to invite me to hang out with them just to be near him. However when she is at her mother's house its like I don't really care anymore what happens to them. Does this mean I like him? And if so what do I do? Is this normal?
