More than just a friend

Don't be afraid my friend. There are so many ways of killing a cat. For all you know she also love you but since you are the man you have to make the approach. i suggest that since you have been friends its not going to be easy telling her verbally about you feelings for her nowadays. Just start by buying her gift like cards,flowers etc.and present it to her in her nice mood time. By doing these you draw her attention about your feeling and i promise her reaction will show whether she also loves you or not. It's not always the best to propose to a girl verbally.Try it!

You should let her know how you feel, if you don't take the first step you'll never know if she have feelings for you too. Maybe she likes you also and would go beyond the friendship you have. Ask the help of some of your common friends...maybe they can patch the two of you. Good luck

Its nice to hear that youve fallen in love with your bestfriend, its not bad, unless you talk to her nicely, and its nice that you know your attitude and its not hard to adjust on some things. Go for it.
