So if you feel like taking risks and confessing what you feel, go on.
This is the worst pitfall of being in love with someone you are deeply connected with as friends.
Getting into a fight is also a whole new battlefield once you are in a romantic relationship and you better get yourself fully armed before going into it.
There are better chances that your best friend will not appreciate being a replacement. It would spare you tons of disappointment if you would know the worth of your friendship. You have got to prepare for the worst-case scenario all the time.
In this case, you have to be totally ready to accept rejection. There will be lot of times when you would feel like you are being led on something wonderful. Guys sometimes feel like being extra sweet without really meaning something else.
Things are not the same once you become boyfriends and girlfriends.
