I am an INFP and my (male) INFJ friend has started acting strangely around me, but not around any of our mutual female friends. Sometimes he'll see me in the cafeteria and sit at a different table. Sometimes we'll sit together and communicate perfectly, and other times we'll have uncomfortable "conversations" where I try to think of things to say while he appears to be deep in thought. I think probably we're both trying to think of things to say and/or overthinking the situation. Other times I'll catch him staring at me thoughtfully, usually from a distance- when he does it in the middle of a conversation it usually derails my train of thought. Does this sound familiar? If not, how do you flirt?
