Suicide Threat? Nick Gordon Tweets Desperate Message To Bobbi Kristina Brown: 'I'm So Hurt I Wanna Do Myself In'

Nick Gordon's Twitter messages grew increasingly sad and desperate on the eve of Bobbi Kristina Brown's 22nd birthday, including one posting that reads like a suicidal threat.

"I'm so hurt I wanna do myself in, I know I have to strongsic," Gordon tweeted Tuesday evening. His lawyer did not immediately respond to RadarOnline.com's inquiry about concerns for his safety.

Gordon has not seen his girlfriend — whose birthday is Wednesday — since she was rushed to an Atlanta hospital after he and a friend found her unresponsive in a bathtub on January 31. Her father Bobby Brown has rejected Gordon's repeated pleas for a visit to her bedside at Emory University Hospital, where she has been in a medically-induced coma for weeks.

"I love you soooooooo much plz wake up," Gordon tweeted earlier.

Along with the pain of separation from his girlfriend — who called him her husband — and her tragic medical condition, Gordon must deal with a criminal investigation into what happened in the days and hours before she was found in the tub.

He has not been named as a suspect, but tweeted Tuesday, "You all blame me but I tried my best and it wasn't good enough for you sorry."

As RadarOnline.com reported, the couple's close friend spoke out from prison earlier this week to defend Gordon and insist he treated Brown well throughout their relationship.
