Nick Gordon has expressed how much pain he's in following the death of his long-term girlfriend Bobbi Kristina Brown.

"I look at our pics sometimes it makes me smile sometime I cry @REALbkBrown #happymemories," Gordon tweeted Monday on his private account, according to Extra. "I'm so happy/blessed that I had @REALbkBrown in my life. i will always & forever love you."

That marked the first time Gordon has spoken out since Bobbi Kristina's July 26 passing at age 22.

Bobbi Kristina's family reportedly held a funeral for her August 1 in Georgia and then followed it up with a second gravesite ceremony a few days later in Westfield, NJ, where she was buried next to her mother, the late Whitney Houston. Gordon was not allowed to attend either event.

Earlier this month, Bobbi Kristina's conservator Bedelia C. Hargrove filed an amended complaint against Gordon, accusing him of causing Bobbi Kristina's "wrongful death."

"We will continue to pursue justice for her," Hargrove told People in a statement last week. "I have filed an amended complaint against Nicholas Gordon adding a count for wrongful death and for pain and suffering. We will leave no stone unturned in seeking justice for Bobbi Kristina Brown."

The initial complaint Hargrove filed in June claimed Gordon was guilty of physically assaulting and robbing Bobbi Kristina of thousands of dollars. Gordon also allegedly pretended to be her husband in order to control her interactions with people and finances.

Hargrove's new lawsuit lists some very disturbing details of the events that allegedly transpired leading up to the moment Bobbi Kristina was found in her Roswell home's bathtub face down and unresponsive on January 31.
