what does it mean when the guy you like stands off to the side behind you?

you can't really tell from that.

but here are the options"

1)he wants to be near you

2)he just wants to stand there

3)he wants to feel comfortable near you

4)he is trying to get the guts to talk to you

I'm not there so I don't really know.

It means he is located in a specific point in the fabric of space. However, this point is constantly moving the continuum of time, and therefore, he is there but not there all of the time. This means several things. 1. His matter leaves behind an antimatter imprint where he was standing. 2. He has experienced that point and time through the electrical synapses in his mind. 3. He has once existed

From these 3 points, we can derive that he exists but does not exist, as his thought is present, his matter is present, but he is no longer in sight.

This brings us to a funny case. Because you know he has experienced, but at any given moment that he is out of sight, his state is unknown, he is both alive and dead. This is the same case as with Schrodinger's cat. Since he is both dead and alive until you next see him, you cannot know for certain if you will again see him. Now this means 2 things for you. 1. You can worry. 2. You can stop caring about him.

This is where the answer to your question comes in. His positioning there at one point in time and space means that you either care enough to worry about him or you don't care about him. Which do you feel?

However, you have synapses in your nervous system which is keeping everything functioning. At any one time, they can be indicating that you worry and don't care. This means you feel neither, since each cancels them out. Therefore, your question is moot.

Quod Erat Demonstratum.

under what circumstances? At a party, he is being attentive, he is allowing for you to stand in front and be the attention. This is very respectful, as long as he doesn't squeeze your butt or anything. Maybe he puts his hand on your lower back, or elbow. These are all nice respectful things, like opening a door. If you aren't in a relationship and he does that, it's kinda weird. He must be either very shy or something. Try a conversation and see what he does.

hes either admiring your view from behind or hes gonna let you get the first hit if anything happens

Does it mean something? It is hard to answer this without more information.

If he's ALWAYS near you wherever you go, then yeah he's definitely there for a reason.

He's checking out your butt~!~
