not急吼吼, this guy aparently

is not in the position to say love this word yet, for whatever the reason.

my personal experiences, after 3 months, still not falling in love yet, normally it will not happen.

Of course, there are other cases.

from what the LZ says, she feels like a call girl. Her instinct is number one important. If the guy is still trying to get to know her, he should say so. Instead, he says it is a strange question... it only shows that he knows he does not love her but makes the girl feel that was a stupid question so that he could get away from telling the truth. Personally I do not like this type of guys, they are not being honest and straight forward. Quite often, they are experienced players.
