Nick Gordon remains focused on seeing his girlfriend Bobbi Kristina Brown as he exits rehab.

Gordon entered a drug rehab facility in early March after appearing on the Dr. Phil show. He's now back home living with his mother and wants to see Brown, according to People.

Gordon returned to Twitter for the first time in nearly two months, writing on April 23, "Back like I left something." His last tweet before that came on March 4, wishing Bobbi Kristina a "Happy Birthday."

He tweeted again on Monday saying, "God grant me the serenity to accept the things I cannot change. The courage to change the things I can and the wisdom to know the difference."

The Houston and Brown families have banned the 25-year-old Gordon from visiting Bobbi Kristina at her long-term care facility in Atlanta. She remains unresponsive after she was found face down in a bathtub on Jan. 31.

"He is very distraught over what is going on," a source from the Brown family told People when he entered rehab. "He really wants to see her. He is upset about a lot of things: her being sick, him never getting respect [from her family]."

Her grandmother Cissy Houston revealed on April 20 that Bobbi Kristina has "irreversible brain damage," which contradicted her father Bobby Brown, who said his daughter was "awake" during his concert on April 18, according to People. Houston also confirmed her granddaughter was no longer in a medically induced coma, but still has a tracheotomy.
