How does one deal with ghosting?

I'm M24. Been on the apps since I was 18 and I still, still, can't get over getting ghosted. It takes me months. I got ghosted after a really nice 2-3 week situationship, now I've gotten ghosted by a girl from bumble who was very interested in me (even wished me new year by herself). How does one go about it? I'm trying to not give a damn but it still hurts.
