How do you think is the best way to break up with someone?

Only two of the options you gave is being the kind of person you should be. The rest are totally irresponsible. If you can't face the person you want to break up with doing all of those sneaky things will get the job done but you will have proven that they are much better off without you. If you were man enough to get her interest in the first place at least be man enough to tell her why you cannot continue the relationship. The worst option? Cheat on her and make her break up with you. You dare not let the one you cheat with know this or they will be gone in a heartbeat. No one who ever knows this would ever trust you again. If you are looking for ways to really do this be the man she thinks you are and just tell her. It can be on the phone or face to face but all the rest reflect the giant chicken you would be.

i think this is not a good thing so better keep away try to make friends not breakup. have a great day with friends and lively life
