what is the best way

There's no such thing as best way in breaking up.Every break up will live a mark of pain.Unless you don't love the person anymore or he/she had done a bad thing to you that's unforgivable then maybe it would be easier.But if you still love that person but for some reason you need to break up with him then the hurt should be accepted.Just do it in manner that he/she fully understand the reason for breaking up and be honest with your reason.Don't just make-up reason like you'll be breaking up with her because your not ready yet for a relationship where in fact there's somebody else you want to take her place because when she found out that would double the pain.Be sincere and tell the truth.Goodluck

There is no way to break up with someone & not hurt their feelings. But then if your the one breaking up there is a reason you don't care about them anymore & you don't really care about their feelings when you think about it. So just say you don't love them anymore & you need to find someone you do love. Don't sugar coat it or you just make yourself out to be a liar as well as a heartbreaker.

The best way is to speak to this person, squarely, face-to-face, and simply tell the whole truth. There is no way that will not hurt a person's feeling with a breakup. It's always painful especially if there was love at least with one party. (^_^) I tried breaking up with someone in a letter, and my ex- said I'm the worst. Hahaha But it's good that my ex- and I are still civil with each other to this date. Besides he was my first so I'm not a master when it comes to relationship.
