This seems to validate the two month theory. This was what Kathryn posted a few days after he died (copied from one of the article links above). Bolded for emphasis.
"I don’t know how to start what is going to be the most painful facebook post I will ever write. I know this is late and I would like to apologize to everyone that I haven’t been able to reach out to all of you before it was released to facebook. On Wednesday, November 15, 2017, the love of my life, my best friend, my closest confidant, Robert Buchel passed away suddenly. I wish I could say that my heart was broken or even shattered, but in reality it is just gone. My heart died along with him. Our future together died along with him. Next year we were going to be getting married in Walt Disney World and have our own Disney Fairytale Wedding. We were going to start a family. We were going to grow old together. Everything we were ever going to be can now never be. He did not deserve to go this way and this was not his time. 14 years together is not enough and although many people say it’s better to love the time you have than to mourn the time you don’t: no offense but screw you. Rob had a hard life and in the last 2 months he finally had hope for the life he always wanted. This was a robbery beyond words. And thanks to those of you who have reached out to me, I realize now that this robbery is more dispicable than I thought. The memories and the love that I have been seeing for him has been overwhelming. I am overjoyed at how much love he had given but also received from all of you. I am also angered beyond words that he’s not here to continue to love and be loved. And even moreseo I am saddened that he died not realizing how much love you all really had for him. Rob suffered from never realizing how good a man he was and always felt inadequate and a failure. Thank you to all of you for validating my love for him. I knew what kind of soul he had but could never convince him of how truly special he was. A person like him should never have to die this way and certainly not this young and most definitely not when his life was about to begin. Arrangements have not been made yet, but his mother and I will be settling things here in Texas as we wait for his remains. Once we have him back, we will bring him home and I promise you that I will notify you when his memorial is scheduled. You all meant so much to him and I thank you all for being there. Please keep his mom and family and friends in your thoughts. This has been difficult for all of us. But most of all, please do this for me: take lessons from him. Every morning he would tell me or text me “good morning angel”. Every phone call ended with “I love you.” Every night he would text me or tell me “Goodnight my love.” In fact the night before he passed he told me “If I don’t wake up tomorrow please know that I have always loved you.” Tell that person you love that you love them. The only consolation I have right now is that we were together and that his last words of peace to me were how he felt about me and how I felt about him. And when he did pass, he was not alone. I was there holding his hand. Thank you to the doctors and nurses who worked tirelessly for almost three hours to bring him back to me. Although I do not know your names, please understand your efforts will not be forgotten. I still have his phone on and his facebook is still live. I will see your messages to him and I will try to respond, You can also contact me directly as well. Thank you all for loving him."
