I'm in love with my bestfriend, what do I do?

I think this is challenging question. I would really question my love for my bestfriend. Is it love as sexual attraction or love as you could love a relative. Sometimes, it could be difficult to differenciate both. Maybe, I would set a bit of distance and see what is the impact on my well-being. If it is a sexual attraction, we need to be aware with two possible outcomes before taking the leap (if it is your decision to share your feelings). 1) Your bestfriend may have similar feelings but does not have the courage to share it with you. In this case, you could potentially start a relationship. 2) Your bestfriend does not have the same feelings and in that case he/she may instantly withdraw. You could lose his/her friendship.
