Take the nerd and shape him into the life of the party! Seriously, take the one who give you what you want and need. Take the one who treats you right - with respect and treats you like a lady.
Seems if you have outgrown the "life of the party.....you are changing, and as you change and mature, your needs change.
Go for the one that accepts you for the wonderful person you are!
Hope this helps! Thanks for the q.
