If you met someone a few times through a friend and they seemed like they wanted to get to know you more, saying we should definitely go for coffee, we should go for walk etc.
So you decide to message them and they read it but don't reply. You try again a couple of months later and once again no reply. Yet you know they're meeting up with others, I know the answer is to stop bothering, I just don't get why people do this whole oh we should go for a drink soon! When they have no intention and can't even take 2 seconds to reply to you.
