It will happen for you also.
In my opinion this is the best way for it to be. At the least you know that she's interested in you - you can then decide if you want to pick it up or leave it on the table. You still need to keep an eye out for any warning signs that she might give off.
Chasing women - them giving hot'n'cold signs - mixed signals - jacking you around - these are all signs that she's not really that interested in you. Only half-assed interested at best. It's easy to dump them when they do that shit with you, no regrets at all. Don't even bat an eyelid if she has a little whine/paddy.
If she was truly interested in you she wouldn't do any of that bullshit.
At any rate, I will keep a close eye on the signals this one gives off. I'm half-inclined from experience to think that she's only interested in me as a meal-ticket. A lot are like that.
