My ex boyfriend (recently left) just got arrested

Today I decided to look up mugshots(he's only had one minor charge so i didn't expect anything) on my most recent ex boyfriend because I was thinking about him, and I figured maybe he did something stupid since we moved out of our apartment. (I still love him unfortunately---he was like my best friend)
So long story short....
I ended up seeing that he got arrested for prostitution, marijuana, and narcotics. 
I have no idea how to feel about this! He looks so much different than a few months ago, I have no idea what happened to change him so drastically. :(
