boyfriend annoying girl -friend

My boyfriend has this friend... we'll call her L and she recently moved to a different state all together anyway she constantly wants to snapchat/text him and call him and most of the time he doesn't answer but now she's asking him to drive up to her state to see her or she bugs to see him when she comes down to our hometown. 
He blocked her on snapchat after she kept sending him pictures and he has asked me if I want him to block her all together on everything including phone # but I feel bad being that girlfriend who says well yes I'd like her gone. 
Is it wrong for me to secretly want her out of his life? He's said Numerous times he's okay without speaking to her ever.
