So ummm ... Rob Kardashian and Blac Chyna are back together! WHAT?! Our heads are spinning!

The on-again/off-again/on-again couple is apparently back after a "heat of the moment" break up, according to Us Weekly.

Umm "heat of the moment" split?! Rob possibly hacked her Instagram, she moved out, took their child and he posted sad sack videos from their empty home! That sounds pretty final -- but we do know when you're part of this dynamic duo that making up and breaking up publicly is just part of your weekend activities ...

A source close to Chyna said, "He apologized to her on the phone. She was just sick of him and his behavior. She had it with his insecurities and jealousy."

After the weekend's dramarama, Rob took to social media yesterday and backpedalled. He and vowed to change his ways for his fiancée and their little girl.

"This weekend I was in an emotional bad place and did some things that embarrassed myself and my family. I apologize and I'm seeking help to deal with my flaws/issues. Please pray for me and I'm sorry @blacchyna. You are a great mother to our child and I love you," he wrote on Instagram.

In another post, he declared, "I am going to get better for you Dream. You are my life and gave me a new start on being a better me. Love you."

Seems like a frothy emotional appeal was all Chyna needed to take back her unstable beau. Umm maybe he should get some actual professional help to deal with his issues? Just an idea!
