Whether it be friendly banter, lovey dovey stuff, pictures, calls, emoji.. etc. Stop caring about someone who doesn’t care about you. If they shy away from your touch they once yearned for.

They stop communicating the way they once did. There are a variety of reasons why you might care about someone who doesn't return that feeling. You may be in a bad romantic relationship, or you might be in the post-breakup stage. Your giving nature is admirable and has probably helped more people than you can count, but you need to take care of yourself and stop trying to change someone who doesn’t want to change. Also, you could have a parent or sibling who doesn't seem to care about you. Because it does not matter how much you love him and care about him, you need to love yourself more. When they liked you it was obvious, wasn't it? Actually, you are doing everything, you are giving your best to make your relationship work. From my own experience I can tell you that the BEST THING to do is to stop caring as fast as possible. You need to understand that it is just a waste of your energy. Your title and the content of your question do not match up exactly: there is a difference between someone who, in a given situation, is indifferent to a certain outcome, and someone who doesn’t care about anything at all.
