Why is it...the nicer my H gets..the more my suspicions peak?

Nice..flirty,charming emails throughout the day today. I cannot say I wasn't enjoying it..but my mind has now shifted to motive..why all of a sudden? H is going to the gym..and exercise has always made him feel better...but he is being a completely different person. He is being my old H..I am not ready to accept this craziness!!!! I've got one eyebrow raised. 3 days ago he was moving to the Middle East to escape his horrid life...today he is happy as a pig in sh*t...I am probably exaggerating..but a notable difference in his demeanor. hmmmmmm.
