How should I handle this?

My husband and I met through facebook. We dated for a year and got married. I am now pregnant with his son. Today I was browsing on facebook... of course I went to his page and when i saw it, I was disgusted. He last chatted with an ex girlfriend from highschool on his wall...and from the looks of the convo... he initiated it... then I look a his pictures and he updated them on April the 6th and he puts a picture of his chest(he has a six pack) and the top of his drawers...( basically trying to attract attention from skanks:-/)...Plus he is still adding friends. Also, NOT ONE picture of me on his page! I I think its very inappropriate that he is still so involved with facebook and coincidentally, that's how we met. He also recieved a facebook gift from some chick that gave him a heart with a key. WTF?! I am so incensed right now but we are newlyweds and I don't want to over react or come off as irrational. How do I handle this... I feel like retaliating :-/
