Is 5 months a long time to wait to see each other in an LDR?

So we've been long distance before but only for about 1-2 months. But people are saying that 5 months is too long and it won't work out. We're seeing each other in May. And we talk everyday and things seems to be going great.

Why are people so rude about this?
