It seems to me that most of you people approach this, like she's an evil witch trying to collect all the souls she can, to present them like a gift to Satan or something.
Haven't any of you just considered the fact, that she might just a regular person with some concern for her ex boyfriend, and some curiosity on how he's doing. Expecially considering that he was pretty beaten up about the whole breakup.
For her to notice his departure is nothing short of normal behaviour. Wouldn't any of you be a bit curious about seeing your ex after so long, especially considering the circumstances?
The way I remember the initial threads about this breakup, was that it had nothing to do with her being mad, spiteful, vengeful and all that. She ended the relationship, because she fdidn't love him anymore. Not because he cheated, abused or did something terrible. If that where the case, I would agree with the sceptics here.
The not that she left, shows IMO a bit of decency. With this note she tells him that she knows/suspects that he's still hurting and is therefore giving him a heads up regarding the softball game. She's not gonna put her life on hold because of this, but is giving him a choice to decide on attending this softball event, with the knowledge of she being present. I think it shows maturity. But I may be wrong, I may be reading this incorrectly. But I think I'm on to something.
Mr. Lestat, in my honest non-professional opinion. I think you should go, I think this will not only make you stronger, but it will also make you take the first/another step towards "recovery" (in lack of a better word). Avoiding her will not solve anything, and in a way only make things worse.
Whatever you decide, good luck
