How do I break up with my girlfriend without making her cry

i dont feel like our relationship is working out so I decided to break up with her how do I do it without making her cry we have known each other for years we were the closest friends ever before we started going out and I want it to go back to that I do not hate her at all

Our brains don't have a feature like Windows "System Restore." You can't roll back the clock and make everything like it used to be. You also have no control over how she will react when she gets the bad news.

Instead of just announcing, "it's over," I would suggest you talk to her about your expectations and why you think it's not working. Just be honest and try to make her understand how you feel and why. She may not be happy with it but your chance of keeping her friendship is much better if you put everything on the table to help her understand.
