I had these one close friend. We had inside jokes our minds

I had these one close friend. We had inside jokes our minds were one etc. but lately it seems Im slipping out of her mind. Our inside jokes are now everyone's joke. It used to be 4 now it s 3(im the one left out) but funny how when a problem or past reappers she comes back to me for advice. Then goes off running again. And recently there's nothing. I know im completely forgotten and im trying to suck it in. Cos this always happen, the ones i thought are my closest friends will eventually leave me. I tried my best to be the supportive positive friend but it seems its never enough. And this lonely feeling sucks. Its like everytime i make a friend, it disappears. Im literally alone.

I'm sorry to hear you are in such distress. It is good that your are trying. I'm here to listen.

@MatthewAOTA should i confront her and tell her that how she’s treating me is just painful? Or would it make it worse, making more distance between us?
