Why Am I Emotional?

I just want to share my story so that I feel a little better. Do you think it's appropriate to abandon your friend when you have found someone you like and wish to marry? And do you think it's appropriate to abandon your friend when he/she doesn't have the same interest? That's what happen to me. I really don't want to tell you about my friend but my patience has reach it's limit point. So, here goes nothing. My friend is a she. She likes to sleep and since we are university students, after class, she will immediately lay on her bed and call her boyfriend. With her unlimited calls, she doesn't have to end her call between her boyfriend. Like when she sleeps or he sleeps, they never end the call. And it become hard to communicate with her. It's the same in class, she even has her earphone on when the lecturer are giving lectures. For me, IT'S very rude. She's being rude to me and the lecturers. I am so not liking her attitude, I don't even know whether she is talking to me or to her boyfriend. One more thing I cannot tolerate is that she is not a morning person so she always get up late. I don't like people who spend their time on the bed. I can't remember the last time she sat on her chair and do her work on the desk. Also, when I go somewhere alone, she doesn't bother to call me where I've been. She can do that with her unlimited call, come on. Every time she disappears, I am the one who has to call her and I'm jealous that she can spend her calls on her boyfriend and my other roommate instead of me. She did ask me to always advice and remember her of something she did wrong. You know what? I did, I nagged her and she must be annoyed of me right now. But, I don't care, it's my duty as her friend and she is the one telling me to advice her. Like this morning, I went out to the library and she didn't bother to ask where am I going. And she called someone when I am going out. Last time, she was jealous of me because I got a full mark on my test and she didn't. She was upset because her effort is just that mark. So from now on, I don't want to wake you up , remember you to perform your prayer and ask you where you are going. I will change if you change you attitude towards me.
