Why are older women not as needy as younger women and more willing to give men space to do their own things?

I became friends with many women, younger women are needy, expect texts, meetings, etc...
but older women do not mind giving you space to deal with life, they expect the same from you, they however expect both sides to respond when contacted, but they are not needy and won't change no matter how distant you get.. why older women are more willing to give men space?
