If relationships suck, why does my father daydreams about walking me down the aisle?

I find that contradicting. My own parents admitted that relationships aren't what they used to be and it's sucking for everyone.

I'm a virgin (well I'm 17) and during a brief conversation with my dad, he said was it's better for me to wait and I won't gain anything by being a man's long-term girlfriend. He said ''You will lose catastrophically (he actually said that word louder and slower) if you don't use your time wisely, your time is limited''.

If relationships are so bad between the genders, why is walking me down the aisle one of my father's dreams?

He's been saying that ''one day I'll walk you down the aisle'' line ever since I was a kid.
