Not just anyone but say like someone you've obviously invested time in. Whether that be like an Ex, Crush, Someone in a sh*tty relationship or just some random person who you happen to be interested in. Because I feel like the longer I know that person the harder it is just to drop them.

You don't need to drop them, just realize that friendship/romance/whatever relationship is a two way street. Eventually you get tired of making effort for people who don't make an effort for you. Same thing here. I used to do a lot of effort to meet up with certain people but when I don't text/call, they don't text/call, so then I started to see how long it takes for them to contact me and well, I haven't heard a lot from them since. Lesson learned.
It's hard but just give yourself time to deal with it. Distract yourself and try not to think about them.
You get tired of making the effort all the time.1
