Rey is a Kenobi
Ben Ostrower

Something that also lends to this theory — in the Star Wars comics that Marvel are running right now, Luke goes in search of Obi Wan’s journal and a full issue of the comic is spent telling a story of Obi Wan on Tatooine and how hard it was for him to forget how to be a Jedi, but it was something that he had to do in order to keep Luke safe as he was growing up.

Plus, Obi Wan did have a love interest in the Clone Wars, although she did later die. She wouldn’t be the mother, but it does confirm that he did struggle with emotions like every one else.
