Rob Kardashian is heartbroken following his split from fiancée Blac Chyna just one month after the birth of their daughter.

The KUWTK star took his fans on a tour of his empty house following their breakup, which was prompted by an Instagram hack that allegedly exposed Chyna's mean private messages.

"I thought this was going to be the best year of my life," he wrote, "had a beautiful baby Dream and haven't spent Christmas with family in years and I just can't believe she really hurt me this way. She knows how to hurt me and I loved her so hard like I'm supposed to. Like any man is supposed to love their Wife. Chyna knew exactly what she was doing to get me."

The 29-year-old continued, "I can't believe she did this to me. And this isn't for some ratings this is my real life so please understand I'm just being open right now. Cuz if it was for ratings I wouldn't explain all this here. And with Chyna's messages and her leaving with everything and the baby I am broken. I go 1000 percent for my girl. I am so confused how a man who gives and loves everything about a woman is the one left alone."

Rob went on to explain that he fought his entire family for Chyna, 28, and didn't know he was "just part of her plan."

"I am so broken," he added. "This is a woman I fought my entire family for. I was in love with this woman to the fullest and I was none of that to her."
