He makes a good point about Juan Pablo sending mixed signals. Especially when he changed his mind at the end of that group date to kiss Claire. He might as well have said I'm just not that into you to the girls he refused to kiss.
I don't personally see what Nikki has been doing that is so bad. Yeah, she can be whiny but so what. Who hasn't whined when it comes to the Bachelor/ette. No one really likes sharing their significant other even if they should know better since they signed up for this.
Oh no! I just did what Juan Pablo did. I just talked out of both sides of my mouth.
