I think one of your problems is talking about the future and how she's the best girl ever after only a few months. The honeymoon period, in my opinion, can last two years and is rarely shorter than a year. What's the point in rushing?
I agree with Indi about being scarce. A woman loses interest in someone if she can have access to them at all times. A woman wants a man with status and you don't have status if you have nothing going on.
