He cheated on me..

I gave this man every single piece of my heart and trust, and he cheated on me with MY BEST FRIEND. 
It's really fucked up. It's reality too... You could be the most beautiful girl, cool, supportive ect girl in the world, and it doesn't mean shit.. Some guys will never appreciate what they have.. I feel crushed; not only the man I was dating for 2 years caught having sex IN MY BED but with my BEST FRIEND THAT IVE BEEN FRIENDS WITH FOR 10 years.. I don't know if it's a dream or reality anymore.. I gave him all my trust; God only knows what he did when I thought I could trust him every time he went to parties and told me to stay at home, or went to giant gatherings without me; or when I was away for work.. I feel like I don't click with anyone anymore.. In his hesitation, I found my answer. 
Now that's it's been 2 weeks, some days I feel everything. Other days, i feel nothing at all.. I don't know what's worse; drowning beneath the waves, or dying from the thirst.
