as she approaches 30 she becomes less and less attractive, period. a 32 year old is not as ripe and thus not as appealing as a 22 year old.
secondly, the older women get the more they feel like "settling down" and yes all women feel this as they approach 30. she even told me "im not 21 anymore im not just looking to have fun im looking to settle down"
she knows what's around the corner. she's probably peaking as far as her appeal goes, because shes not old yet but is old enough to have her own place and a good job. when she's 30 there will be a new flock of women in their mid 20's who will be more appealing
