You and your ex may have parted on bad terms and have not spoken for a while. While you are not interested in getting back together with them romantically, you may be interested in reconnecting as friends. While being friends with your ex can often be complicated, being clear about your intentions from the start can help establish good emotional boundaries. Get in touch with your ex and make sure they are willing to try to strike up a friendship. Arrange for a meeting if possible. Then, if all goes well, figure out how you would like to stay in touch with each other. While it may take work and may sometimes feel awkward, especially at the beginning, rebuilding a friendship with your ex is possible if both of you are ready to work on it. 
Yep, I’ve definitely had to learn to deal with plans in a completely new way. Seems life was intentionally setting me up to learn when and where plans were useful. One of the main points was to learn to set an intention for a direction or path. Then, while making my way along said path I had to learn allow influences and changes to the path to flow. Being attached to how things should be according to my plans, would choke off the creative possibilities. The unplanned possibilities were typically better than anything I came up with on my own. The unexpected has become the expected to the point of seeing it as an important part of any journey.
The film received a generally favorable reception from the fandom and a mixed reception from critics, with some feeling the film focused on certain aspects of fandom and ignored other facets, including the lack of criticism of the fandom by others, and the significant portion of female adult fans, occasionally named "pegasisters". Other fans felt that the documentary made the concept of being a brony mean that one had to be "treated like a misunderstood taboo to the rest of the world", and countered that they have openly expressed their appreciation of the show without any backlash from friends and family.  Jeneé Osterheldt of The Kansas City Star stated that "the film does its job" in showcasing the stories from the fandom, and that it "makes you think twice before judging a guy by his cutie mark".  Mike Sauve of Exclaim! states that film, while showing some of the more touching aspects of the fandom, "plays like an infomercial for [ My Little Pony ], fawning over its creator and voice talent".
