A lot of people accept the "request for friends" because of how facebook is set up. However, that doesn't mean that accepting suddenly gives the other person a right to get into that person's private life and it doesn't mean that suddenly there is an agreement to constantly connect everyday either.

It sounds like you are a bit more extroverted and this guy is introverted and likes to be more private. He isn't being weird but is merely expressing his need for others to respect "his" space.

From what you shared in the other thread, you drank a bit and went and sat down with him and began to get more and more into "his" space. Then he got angry and got up and left to which you insisted on following him and getting into his personal space even more. His reaction was anger and expressing how you don't get the hint and back off. This guy sounds like a private person that doesn't like it when people get into HIS SPACE. This is important to understand about other people that express a need for space toughbird. Every time you interact with this guy you begin to get into his space and he makes it a point to create space with you by not interacting with you at all.

While you feel this is not normal, the important thing to understand is that this is normal to HIM. What you consider normal is being more extroverted like you seem to be but that's normal to YOU. This guy is not a good match for you, you need a person that is more extroverted like you are and it's important that you understand that you are not going to ever change this guy to fit in with how YOU like to interact. Your presence is too strong for him and you need to learn that there are people that will look to create distance and space from you because you are too extroverted for them and tend to get too into their space. He prefers HIS friends to give him as much space as he needs, he is consistently showing he is sensitve to individuals that get too much in his personal space.
