What's the best way to stop caring about someone who doesn't care about you ?

This can be something very hard to do! But when I was in a situation like that I just thought about it this way...Why should I keep putting my energy and love towards caring for someone who doesn't care about me. It was really hard to do but I had to realize that it was best for me. This quote also made me realize that it was best to let go "It hurts to let go but sometimes it hurts more to hold on."

Find whatever it was in them that made you care about them so much, and start looking for it in everyone you meet. You might find it's not as rare as you thought, and that there are other people that have those characteristics and will return your affection.

Believe them. And leave. Don't beat yourself up about it. If they don't care about you, and it seems like you're not even a bit important to them, leave them be. Just ignore them. That's probably the best way.

Dare to place yourself in his/her shoes for a moment. Consider yourself, from their perspective. Think of all that is wonderful about you, all that makes you you, all of which you are proud. Add to that the fact that this person has the privilege of being cared about by you. Now, still in the shoes of this person, let this all wash over you thoroughly, and in the end, say (as if you were them): "I don't care about him/her." Let the cold, brutal reality of that statement run down your spine. Life is short. Don't pass up the chance to enjoy being cared for deeply by wasting energy on those who will not do so!

You don't forget about them. You should just keep a mantra to yourself saying that you want to stop caring and tell yourself the reason why you want to stop. Based from experience.

Realize is not worth the heart ache and stress having to think about something that upsets you. Know that the most important person in your life that you need to care for is you.

It sounds like you are upset with someone as you do not feel that you are being cared about. Is that so ?

Don't talk to them temporarily. You need to not think of them. You can't get over them if you're still talking to them. Delete their number, pictures, EVERYTHING that reminds you of that person. You need to rid your life of them, and when you realize you don't care about them anymore you be their friend. And if they still don't care about you enough to atleast be your friend, don't ever waste your time on them again.

The best way to overcome a relationship that is not reciprocal is to recognize that healthy relationships are equal. The best relationships, whether with friends or romantic partners, are the ones where both people give and take equally. Those are the relationships that you should nurture and grow. Imbalanced relationships will only cause harm and negativity in the end, even without intent. However, it's important to also realize your capacity for Love. At some point most of us will experience a non-reciprocal relationship. During these times it is important to recognize that you are not doing anything wrong by having feelings for someone who may not feel the same way...you are only demonstrating your capacity and ability to Love. And that is a beautiful thing! Most people will appreciate that whether they feel the same or not.
