"The Neptune person can come on strong at the outset, and then slowly fade away, or in some cases abruptly leave. Most of the time, he or she hangs around, whether physically or (and most of the time) psychically. It’s hard to get the Neptune person out of your system, mainly because there can be a lack of closure, a lack of answers as to why that person “faded out”, became inaccessible, or disappeared."
