Cole has been in a relationship with AEW Superstar Britt Baker for several years, and he has several friends in All Elite Wrestling. For these reasons, fans always knew that there was always a chance he could make the switch.Cole's departure was a huge mistake on WWE's behalf. The company lost a main-event-level talent due to a clerical mistake; WWE officials forgot that his contract was expiring.Cole told Chris Van Vliet as part of a recent interview that he had the chance to think about his future with the company when he found out his contract was ending. He noted that leaving WWE was a very difficult decision because he had a great run in NXT."I want to make this very clear, and I know that everyone knows this, I had a wonderful four years at WWE," said Cole. "Specifically down in NXT with Triple H and Shawn Michaels, two guys that I respect the hell out of and have been nothing but so kind and so generous to me.... So the decision actually was difficult in a lot of ways."Adam Cole's contract with WWE officially expired on August 27th, which allowed the former star to make his debut for AEW at All Out on September 5th.
