ILI-INTp dating behavior

[Skepsis]

My (SEE) friend met this guy and I think he is ILI (he looks like one plus other clues). I am curious as to what dating behavior (or generally behavior of an ILI who might be interested in someone) one can expect from ILIs? Anyone?

I have never initiated unless it was clear the girl I liked was interested in me. This is very hard to tell and I would struggle with whether or not those behaviors are clear signs. If they would've just told me they liked me that would've solved everything. However, if a girl was too demonstrative and I didn't like her before that point, I often would try to avoid her. As a general rule, I must like her first, then see if she likes me in return.There was once a very pretty, very intelligent girl in high school that I doted on. I wanted to ask her out so bad, but instead asked her if she wanted to dissect a heart with me for extra credit. I was so nervous. I first like to see if they will do something of interest with me and then just see where it goes from there.
