I'm with nisaba on this one. I think the cards come out just in the way they're meant to but we aren't infallible, no matter how long we've been using the cards.
I think there are some here who don't agree when I say this, but I still maintain it to be true----the cards are always right. We just don't always read them correctly. Maybe because we want something to be true so badly or maybe we're over-thinking instead of being able to be objective----whatever the case might be.
Another factor could be in the element of time. It's possible that ultimately, sometime in the future, you may become a couple even if you aren't now.
Those cards that you mention being repeats in your draws about this may mean something different than you think. Sometimes the 2 of Cups indicate a friendship, not a romantic relationship. Sometimes the 9 of Cups indicates maybe there's some problem drinking. Page of Cups can point to immaturity or the conception of a child.
Do you use reversals? If not, this may be a time when you'd need to consider the reversed meaning of the cards instead of the upright meaning.
To get a more objective reading about this, maybe joining the reading exchange is an option that might help you out. There are always tons of people using that sub-forum and it's very helpful.
