That sounds right. No two things are the same. Makes sense to me.
Well, I always believe the woman will be quicker to love the man for who he is and will love him more then he loves her. It will go deeper for woman then for men.
How can we quantify love?
We show love in different ways. Some with words, some with touch, some with deeds, etc.
We need more info to at least give a reasonable suggestion. If you are trying hard to make the relationship and she says that, then she may be saying that she is not too interested, or that she can't express her love as much. If she just says that out of nowhere or possibly when you guys are having a personal conversation, then it may mean you aren't showing enough affection.
..that it is like a competition..
and you're on the losing side
