This gentleman was arrested on Monday for attempting to strangle his wife. Bradley Gellert, of Apollo Beach, Florida, was indeed wearing the "I [heart] My Marriage" t-shirt at the time of the arrest. From WTSP:
The arrest report says that the couple were arguing over drugs, and during the fight at their home, Gellert screamed in his wife's face, threw things, grabbed her neck and strangled her, and knocked her to the ground.
