Why are women so much more into relationships than men are...?

The other day I heard my mom and aunt talking about celebrities, and my mom was saying how she had a dream that she kissed George Clooney and it was amazing and my aunt was saying how she also had a dream recently that she married Simon Cowell and was really happy with him (NO I'M NOT JOKING) and this got me thinking, so I started to look at overrated male celebrities facebook pages to read their comments from fans, I went to Brad Pitt, Johnny Depp, Robert Pattinson, Justin Bieber and the Jonas Brothers pages and all the comments were "I'm in love with you <3 <3 <3", or "I wanna marry you!" or "I love your eyes and smile!" but then I went to Megan Fox, Scarlett Johansson, Katy Perry and Kim Kardashian and all the comments were "I wanna bang you sexy b*tch!" and all sexual stuff. Why are girls so infatuated with love and relationships to the extent where if they can't find a relationship they start to think they are in love with hot male celebrities when really all they wanna do is BANG THEM! It's lust, NOT LOVE.
