Mitt Romney's open letter: I love Ann

Washington (CNN) -- Mitt Romney took to the social media blogging site, Medium, to write a love letter to his wife Ann Romney on Tuesday.

Romney posted the public letter after the pair launched the Ann Romney Center for Neurological Diseases, a facility specializing in Alzheimer's Disease, Multiple Sclerosis, ALS, Parkinson's Disease and brain tumors, the Los Angeles Times reported.

Mitt Romney to the rescue?

Romney romantically opens the letter with a photo taken around 1968 in France during his two-and-a-half years as a Mormon missionary. With help from friends, he drew a large heart in the sand, with the note, "I love Ann."

The letter recounts how the Romney learned of Ann's Multiple Sclerosis diagnosis and closes with line, "I could not be more proud of the 15 year old girl I fell in love with almost 50 years ago."

Ann Romney is done, done, done with Mitt 2016

The White House also joined the social media site Medium this week and already tops Romney by over 30,000 followers.

This comes just after Ann Romney told the Los Angeles times that she is "Done. Done. Done" with the prospect of another presidential campaign for her husband.

But as far Mitt's love goes, that appears to be never done.
