Her message follows a tumultuous week of dueling public statements from Gosselin and Glassman, including reports that the couple had split.
Still, a source told PEOPLE, "This was all a carefully orchestrated sequence: First, Hailey laments how hard her life has been lately and how bad Jon treats her, then Jon repents. Next, Jon plans to announce that he is going to be spending some time alone."
The source added, "It has all been designed so that it doesn't seem as though Hailey got dumped."
The Two SidesThis past week, Glassman accused Jon of throwing "mantrums," while he said publicly, "I am grateful for her emotional support, and I regret any pain that my actions have caused her as she has selflessly born the pressures I have endured under the media glare. I am committed to making things right with Hailey as well as [with estranged wife] Kate and especially my children. I ask you to please give me the opportunity to prove myself."
Gosselin then announced that he planned to reconnect with his "deeper, more spiritual, more altruistic self" by studying with celebrity Rabbi Shmuley Boteach.
As for whether Jon, 32, and Hailey, 22, have officially ended their relationship, the source insists this still remains to be seen.
"Jon has said he was done [with Hailey] before, but he basically hasn't been single since he was 19 ... He doesn't really know how to be alone. He'll probably still spend most of his time either with Hailey, or some new girl."
When reports about the relationship flared up on Friday, a rep for Gosselin had no comment.
