How to fix a broken friendship with my best guy friend/crush (Long but read please)?

i think giving it to him on your graduation is a good idea. but telling him that you love him then is a bad idea. why would you waste time if you could tell him now right? every second that you spend to show him your love is every second of act of love that can't be taken from your lives. just have the courage to tell him on what you feel. who knows? maybe you could already step to your next level of relationship. if not, then things will be clear already right? goodluck
