Could there be a more unhealthy relationship?! We think not!

Blac Chyna went on GMA this morning and announced she's getting a restraining order against Rob Kardashian because he won't stop harassing her, both online and in real life, and she claims he was physically abusive. Well, Rob is now saying his baby mama isn't so innocent herself, and actually tried to strangle him during one of their arguments.

Kimmy K's little bro alleges the day the former stripper moved out this past December, she tried choking him with an iPhone cord and hitting him with a metal rod, before Kris Jenner's boyfriend Corey Gamble stormed in and broke it up. He also says Chyna then proceeded to go through the house and smash TV's, doors, mirrors, and other items in a blind rage, causing $35K in damage. He claims he has video of the whole thing.

Chyna is seeking a domestic violence restraining order because she alleges that Rob pushed her to the ground and then broke down the bedroom door during one of their many fights, and she says she also has video to prove it.

Their lawyers will be in court today hashing it out, and TMZ reports the reality star will not contest the restraining order. Rather, he will agree to stop "cyberbullying" his ex. His attorney Robert Shapiro says Rob's social media attack on Chyna was "a spontaneous reaction that he regrets." You can say that again! "Rob's only concern is for the well-being of baby Dream," Shapiro added.

What a nightmare!
