i dreamt that i was on the way home somewhere, walking or biking (i don't remember), and i stopped at this building that reminded me of a school i once saw. i went in and went into one of the classrooms, which happened to be for a shop class. then i saw my (ex)boyfriend, just standing around. i went over near him and we both just kind of looked at each other, i started playing around with a small block of wood, he leaned against the wall. then this girl walked in, up to him, and they started hugging and kissing, not making out, but coupledom "oh i missed you" kissing. well, i got upset and told him to come outside with me. now, the exterior door of this room led out onto a lake, and we went and walked onto one of those square things that float. he lost his balance and fell into the water. i went to help him out, and i almost fell in, but he held me up so i didn't fall. he climbed out and told me he didn't love me, didn't want to be with me, that he loved that other girl and didn't miss me at all. i cried that whole time, i couldn't believe it. then he went inside and i left, crying the whole time.
