Most guys are too shy to approach a girl even if she is giving him heavy eye contact and obvious signs that she's attracted to him... this boils down to confidence issues, low self perceived value, caring too much about what others think and a plethora of other things. When a guy sees a girl looking at him from across the room and finds her attractive, instead of thinking "sweet, she likes me, let's go!" they bombard themselves with negative shit like:
"I want to but I dunno what to say..."
"What if she doesn't like me?"
"What if I run out of stuff to talk about?"
"What if she's waiting on someone and I look like an idiot?"
"What if people see me approach her and listen to what we're saying?"
And many more...
Even though none of this stuff matters, guys everywhere are shitting their pants as thoughts like these run through their minds. Ironically, if they know you're attracted to them this only makes matters worse because they're so scared of messing up. So, if you want something done right, you're gonna have to do it yourself. And yeah, women aren't supposed to approach men, but that rule can go to hell. If you have some form of plausible deniability for joining him it'll be a breeze - just tell him there are a couple of guys hovering across from you or whatever and you're worried they might come over to you, and ask if it's ok to sit with him for a while. Boom, work done. And I thought girls were meant to be good at this stuff!
