Is there anything i can even do about one sided friendships?

I feel like no matter what i try or what i do all of my friendships just eventually become onesided. Like this recently just happend with my longest tenured friend, who I've been friends with for over 5 years. Around a year ago they just started putting in less and less effort into the friendship and now if I dont text him first we would never talk to each other again. I dont get it, like I am doing something wrong? Why does this always happen with all of my friendships? I tried talking to some of my friends about it and they kinda change for a bit but they eventually just go back to hardly not putting in any effort. I feel like I am doomed to have this poor social life forever.
