What should I feel?
I do not know much about a love relation between a boy and a girl, I do not know what should they share each other: having a private phone number? sharing email password? I totally do not know, but I am shocked by knowing that my best friend’s email is also be able to accessed by her boyfriend. Actually, it is none of my business. I should not feel angry with that, I should not feel anything cos it their business but I cannot stop the feeling I am having now. I shocked. Do all the lovers have to abandont their privacy? I just feel that my friend’s boyfriend should not know what I am talking to my friend, though it nothing secret and I am not talking behind him but I just do not feel right, I totally cannot accept this for this moment. I just wanna shout it out and here I wanna say it here, that I feel not right. Yeah, I feel not good at all. 
I think there are levels of privacy. Giving out the password maybe to check on each other? i’m not sure hehe. but maybe they TRUST lolz. but I think it depends on people. Some don’t really let the other go that far to their privacy. i don’t understand it either.
they should have told their friends that they share email address etc because there are certain things that friends would only want to share with a specific person, not both.
I wouldn’t like it if wrote a letter to my friend but her boyfriend or husband have opened it and read it first.
If you’re not comfortable sharing infor with her boyfriend, then you need to tell her and ask if there is other way to communicate.
@icebreaker: yeah, they might need trust but to me, i just wonder where is their privacy?
@bong soursdey: yeah, you do understand my feeling, thanks bong
