My boyfriend or girlfriend wants to break up with me, how can I change their mind?

You can not chamge peoples mind, you can persuade them by changing but it is their decision on what they want to do.

Well, they'll have their reasons. Maybe they've started to feel unhappy in this relationship. The best way is to ask for their reasons and solve the problem together :)

Are you sure you want to change their mind?

Well, honestly I really don't think that you can change their mind. I mean there is always gestures that may fix the problem, but then you will never know if they are in the relationship for you or because of what you offered them. You can have also have a conversation with he/she explaining to them why you should stay together, but at the end of the day it is up to them to decide whether they want to continue the relationship or not. You can't make someone love you or stay with you. If they decided to break up with you try to find a way to just let it be because the break up is probably for the best and you may not be meant to be with him/her. There is no harm in trying to save a relationship with someone that you love and/or really like, but sometimes you have to just let go and let God. Let time and fate do it's magic and if it's meant to be it'll be. If not it just worked out for the best and you just need to try to move on.

It's their choice. You can't change their mind, only they can. What you can do is tell them you don't want to do so but even then, it's up to the both of you what you wish to agree upon. If the person says no why try and force them with you.

You find out why the want to break up with you. Maybe you have flaws they don't like and maybe you can change them. That is the easiest way

If you have a significant other that wishes to break up with you--let them. Anyone who knows your worth will appreciate you and wish to be with you. If the person you're with no longer wishes to pursue a relationship with you--you both deserve the chance to find someone who will. Begging them back or sacrificing something about yourself in order to convince them to stay-- is not only unfair to yourself but also a means of creating resentment between the two of you. The saying "if you love someone, let them go. If they come back to you it was meant to be, if they don't-- they weren't." is one of the truest sayings I've come across in my relationship experiences. Everyone deserves to be with someone that desires and loves them--no exceptions.

You cannot force anyone to be with you the best you can do is respect their decision(although its very hard to) and let them know that you would always have their back even though you guys are not in contact

There may be a way...but it's hard to change anything where nothing gonna works out...So we first have to make sure if this relationshi really works out where there's only one hand to clap..

It will probably not be the answer you would want to hear, but it's time to let them go. Your boyfriend/girlfriend may want to break up with you for several reasons, but usually it is mostly about them and not you. If there is no way to work it out, it's time to let it go. It will be the hardest thing to do, but set them free. Let them find their happiness and you will find yours.
