Have gotten these and similar lines many times, especially the hot/cold stuff. These only have credibility if the reader discloses specific details along with these lines. For example, in the case of my then ex, nearly everybody was saying he was wishy-washy/hot and cold but only 2-3 readers went on further and picked up specifically that he may be bisexual, bipolar/unstable, and a pothead or other stuff that I only knew or suspected and he was trying to hide. So unless they tell you exactly why your POI has been acting like that and not the general line "he has been hurt in the past" or some other generic BS that applies to almost everyone, you can't rely on these claims alone.
