I feel fairly certain that she did mean what she said, particularly given the fact that she wrote similar kinds of things in her diary (obviously only intended for herself but reported by a friend).
She has had a number of short term relationships but also had a 2 year relationship before me so she has committed in the past. That relationship was at distance the entire time but only a fraction of the distance we had. She was also still at home whilst the bf was at university so less of a distracting/tempting environment.
I feel from all of the evidence that she must have meant everything she said, wanted things to work at distance but just felt the infatuation rose tint fade and took that as a loss of feelings (having never really experienced the same level of infatuation before). I suppose this exposed the reality of the situation i.e. 3 years at long distance and she just handled things badly.
Would you say that to stop texting me, having sent messages such as "I love you so so so much" and "I think I need you; I miss your mind, body and soul" just days earlier, then sleeping in bed with (or maybe sleeping with) another guy and then ignoring me to text him as though she didn't care was bad behaviour? Immature? Selfish? I wonder whether she was texting him in front of me partly to distract from the situation?
What I am concerned about is that she will have a better relationship with him than with me. Or alternatively that she will look at him and think "well if I can have that, why was I with my ex (me) (from a looks point of view)...
