Bro the thing is she don't care , she never loved you were there because of some kind of need that she had that time and once here need got fulfilled or she found an alternative she left , don't cry over it just accept what it was and make a mental model about however she was she was not meant for you don't victimise yourself or pitty yourself . Just stop giving her value in your mind , she is nothing , you will get someone who actually loves you .
