If you're trying to argue that ldrs fall apart frequently, consider that most in-person relationships also fall apart pretty quickly. How well a relationship works is based on each person's personality type and their compatibility with the person they're with, which can take anywhere from a few weeks to many years to find out if they're actually compatible. Saying that you shouldn't get into an ldr just because they tend to fall apart is pretty silly, most relationships fall apart.
typically real-life relationships are more defined, because you personally know your partner, you know their flaws and their attractive aspects. if you get into a sticky relationship, it'll end fast, but if you find the perfect person, it'll last a really long time and be fulfilling.
in an ldr, the lines between those two are entirely blurred. unless you already knew the partner and everything about them prior to the ldr, you'll really idealize them. so you can really be in a long distance relationship with a stuffty person and not know it until you meet them irl. as i said, its a crapshoot, and a lot of teens tend to idolize LDRs to stuff until they realize how hit and miss it can be
it really depends on who you are. if you like ldr, then that's fine, but the chances of it forming a real fruitful relationship are very very very slim. some people just like love, some like the money, it's all preference. either way, you can quantify the differences between stronger and weaker relationships. for example, liking someone only for their money is obviously a less real relationship that liking someone for who they are, their loveual experience, and their financial situation. liking someone through ldr is objectively less real that liking some in real life, unless that real life relationship is friends with benefits or sugar daddy/mommy
