There is no right way. No matter what or how you say goodbye it hurts. The best way is to be honest, just lay your cards on the table. Try to be gentle, explain your reasons if asked thank them for everything & move on. Don't reply to calls or text from them, it just lengthens the grieving process & they might try to guilt you back in. Once it's over let it go
There's no good way to end a relationship. My suggestion is to be honest and true and end it with the hope of still being friends. Me and high school sweetheart broke up over 15 years ago and today we are like best friends.
Unless you fear violence from your partner, always end the relationship in person and avoid ending the relationship during a row or when highly emotional. Tell your partner you need to talk to them. Don’t let them think that you are planning a nice intimate afternoon. Choose a neutral place rather than somewhere you share. Deliver the news calmly and clearly, convey that you’re serious, that it’s definitely over. Avoid blaming your partner or criticizing them. Keep language as non-emotional as possible. Keep the word “you” out of it as much as possible. Express regret that things didn’t work out. And remember, if things are wrong for you, then they too could actually have a better relationship if released from this one. Avoid clichés. No one wants to hear: ”It’s not you, it’s me!“ or ”You’re really nice, but…“ or ”We can still be friends” (you may be, but now is not the time to discuss that). Nor does anyone want platitudes like: ”You’re bound to meet someone really special who is more right for you than I am…“ Just stick to the facts of the matter.
Be truthful and try to avoid finger pointing, concider your partner may be devistated and be ready to handle it. Make it short and sweet and dont look back. Dont bombard with lots of because's pick your substantual reason and stick to it and you should do it in person unless u r dealing with a threatening person send them a text or email.
its very hard trying to end a relationship the right way, i know this from personal experience, just say that you need to talk to them, be nice and respectfull, but dont goo goo or sugar coat anything, be strong and firm, but not disrespectfull,
