first boyfriend

My youngest daughter was 2 when she started daycare. By the age of 3 to 4 she talked about Alex, he was her boyfriend for :"years" she talked about him all the time. one day i noticed/overheard her saying something about kissing him.
This is the daughter that has learned she can not lie but she tries to change the detail to make it sound acceptable. so my first question was did you kiss on the lips? kinda. then i asked for more detail she kept backing the story up to having it that he just kissed her hand. I gave her the "talk" about her age and dating and ect. But they did go so far as getting married. she said that she had to wear her white lacy dress and he was wearing a suit and he had a ring for her and their friends acted as preacher, best man, brides maid, ect. the day care had a gazebo and they organized that they would walk into and have the ceremony. the teachers said that it was so sweet and that all the kids did all the organizing and preparation. She left the daycare at 4-5 and she has seen him since but she refuses to talk to him. when she was in high school they had to do a job shadowing and she chose that daycare. she came home talking about how familiar it was and how she remembered all the activities and different rooms, oh and the closet was still there that she and Alex used to go into to kiss.
