I think observing how fast the "signs of love" develop is a useful heuristic in determining how fast they could dump you. If a person falls in love with you even before you have demonstrated your worth, something is wrong, assuming you're looking for a longer relationship. I personally think this works the other way too, I don't think falling in love is a useful heuristic for finding a suitable partner. Some people are just addicted to falling in love, and when it starts to fade, will look for their next rush.
(Edited to be sex-neutral and added explanation. Men fall in love too, and I'm not saying you or her didn't have good reasons to.)

Ehm... ok! Nobody said s/he didn't...?

In my case the 'courtship' phase, let's call it this way, lasted about two months. In your experience this is too fast or the correct time for assessing correctly someone's interest?

Information that surprises you is interesting as it exposes where you have been miscalibrated, and allows you to correct for that.
I suspect the users of LessWrong have fairly similar beliefs, so it is probable that information that has surprised you would surprise others here, so it would be useful for them if you shared them.
Example: In a discussion with a friend recently I realised I had massively miscalibrated on the percentage of the UK population who shared my beliefs on certain subjects, in general the population was far more conservative than I had expected.
In retrospect I was assuming my own personal experience was more representative than it was, even when attempting to correct for that.
