Why do libras annoy scorpios?

I'm a scorpio, I've been friends with two libras and I cant stand either one of them. I even quit a job because one of them worked there and i got tired of seeing and having to talk to him everyday. We party on the weekends though! Two days for 5 to 8 hours is enough of libra. At the same time I want to be a good friend and be loyal, so I still got love for them as friends. It's like I want to like them, but it's hard. I don't feel that deep connection type bond that i feel with my other friends. My one libra friend annoys the hell out of me, wants constant attention from any and everybody, even E.T will do, and it gets on my nerves. I'm a people magnet, so i draw people to me effortlessly at the clubs, and he makes every effort to suck them dry for attention, and if they are talking or more interested in me not him, he will gets all pissed with me. He gets his feelings hurt alot, tries to cover it up but i can tell. Sometimes i just can't deal with him and i think he's picked up on it, i do avoid him..He wants to talk everyday! About nothing! He's an air head, no deepness at all, So at times i just dont answer. So he started texting instead, I prefer texting to talking, but now I feel obligated to do that or he gets his feeling hurt when i don't text him back. I can't win. I really don't even want to be his friend, but i feel bad because he's not a bad person and i dont think its his fault he annoys me, that just the way he is. I've never met anyone that I love like a brother, but don't like. I tolerate him, even my other friends notice that i tolerate him. We own a business together so that's the only reason he's lasted this long. We are not speaking again and I'm usually the one to call to patch up the friendship, and this time i just cannot bring myself to do it because honestly I'm tired of caring. Is it worth it to even it to try and be friends with someone that annoys and drains you to the point of misery...even if they are a good person, cool and you can tolerate them 20% of the time? Damn...i'm beginning to sound indecisive i think.....wonder where i mighta picked that up..lol.
