*raises the cheating flag* thats sooo not cool....it says a lot about what she thought of your relationship....it was better in her mind for her to spend the time "apart" from you and with someone else rather than take the time to think about what she wanted from the relationship, what you wanted, where she saw it going in the future, does the good outweigh the bad etc etc....no she didnt think about that....or perhaps she did but she didnt do it alone which in my opinion is kinda the point of the break....bottom line....IF YA WANNA BE WITH SOMEONE ELSE--YOU BREAK UP! you dont agree to a break and use it as a "get laid with no consequences card"! my two pence
BTW i would feel the exact same way....its hard to get an image of yer girl and another guy outta yer head once its in there :(
