How can I move on from a breakup if I was certain he was the one?

He could still be the one.....just later on in life when your souls are ready for eachother. Do what you feel is right....follow your instincts....and ask yourself "why is he the one?"

You're going to need to reframe your way of thinking, which will be very difficult but it's do-able. There are over 7 billion people in the world, that's 7,000,000,000. The idea that there is only 1 person on the entire planet who you can have a successful relationship with is illogical. Further, the probability that you already met that person and things didn't work out seems almost impossible. You will meet so many more people in your lifetime, some of them will be better suited to a relationship with you than others, but eventually you'll find someone who is right for you to be with. & then it is important that you don't get complacent - thinking that he is "the one" can give you an excuse to not work as hard at a relationship because if he truly is "the one" then things will always work themselves out, & that is how relationships with potential fail.

Try to meet someone new. Give someone else the opportunity to sweep you off of their feet and show you that there are more fish out there in the world. You are a beautiful, everyone should get to have someone else sweep them off of their feet at least once.

You both need to be the one for each other; he was the one to you but you weren't the one for him so I'm certain that he actually wasn't the one, you probably thought he was. All you can do is make peace with that and give yourself time to get over him; write a journal of your feelings or write poetry or talk to someone to help you vent.

Allow yourself time to be sad, and you don't have to move on right away. Give yourself space and distance from him/the relationship and look back on the relationship with a more objective point of view. Maybe things were not as you thought they were. Maybe things seemed better because you wanted them to be better. Even if you made a mistake, you are still worth loving and you are still important to people. If he couldn't see that, then it's his loss

Well, "the one" has to be defined with 2 peopl. If you think that person is "the one", and that person also think you as his/her "the one" . Then you two are really "true love" for each other. If only you think that, but the other person doesnt think so ( proof that person leave you already) , then you two actually are not "the one" for each other. It's all misunderstanding in your head. It's not reality.

I think if you break up, it tells more about the reationship... I guess it can even mean he is not the one, so we better accept it and move on...

If he was the one he would be with you. I would advise a goddess year of self discovery to get to know who you are appreciate your worth. Concentrate on a new job, Tavel, image change, do a course in learning a new skill. If he really is the on you will win him back by not being needy but more than surviving. Maybe he just needs to miss you for long enough to realise.

If it led to a breakup, it simply means that he wasn't the one. However, most importantly is becoming THE RIGHT ONE, not finding the right one. Moving on is never easy and it takes a lot of hardships, but nothing is permanent. Meaning, sadness, depression, heart break etc won't last forever because everything shall pass. We are our own master. If you decide and always focused on the sad part, then you will be sad, but if you tell yourself that you will be happy, you'll be able to move on. It takes time and integrity. why hold on to something that's not right for you?

Focus on the positive sides of life. Just imagine how great the future will be when you do meet someone else.
