I was relating a personal experience that feels like men do more for you (wine and dine you so to speak) when they are the ones chasing you. If they already have what they want then they sort of relax and do less sometimes.

But this may not apply to all. I think Divine is right. It could be a number of reasons and if he no longer wants the relationship, who knows how up front he will be. You can't force people to choose you or force them to act certain ways but if you are the one who leaves and they want you to stay then they might reconsider if they really want you in their lives.
