makisali na din ako, pero my opinion is not of the majority.
actually i was just talking to my husband about the same scenario, this was before the thread was even started. sabi ko sa kanya 'as long as nobody involved is married, everyone is fair game'. and before you also accuse me of being a home-wrecker/relationship-destroyer, i am not, have not been and never will, you can go back and check my old posts, there's nothing there, hahahaha. i was talking in the context of a harlot seducing a guy already in a relationship (bf/gf stage), if the guy succumbs, then it only shows how weak he is. temptations are everywhere, nobody has control over the actions of other people, what we have control over is how we react to the situation. and that's exactly the scenario I see we have with TS, pilot and gf.
i actually see where TS is coming from, based on what she posted here. she didn't seek him out, he pursued her. we don't know what the pilot is thinking. it could be that he actually liked TS more and would rather be with her, that he'd eventually end it with the gf. OR he could be the *censored* that everybody says he is and string both girls along.
so the only way to find out is for TS to ask him what it's gonna be.
i'm not saying she's totally innocent with her motives, she admitted to emotional cheating herself. actually this could have been diffused early on if the first time he showed interest (hatid/sundo, casual date), she could have easily called him out and say along the lines of "why would you do that, you already have a gf, what would your gf feel if she finds out?" mga ganon sana so he's forced to show his card right away , pero that's not what happened, she went with the flow bec she didn't want him to think that she assumes too much.
i think that's what the majority here is saying, she kinda encouraged him in a way.
TS admitted to being weak, yes she might be. but i think it's fair for her to ask him now what his intentions are, given that enough substantial proof has been shown for her to assume anything else.
anyway, going back to being 'fair game', it's better to find out now the kind of person you're in a relationship with before it's too late like being married. whatever happens next (after the confrontation) might be best for everyone. if the pilot is a cheater and leaves the gf, the gf is spared of further heartache. if the pilot is honest in his feelings for TS, that is, he's going to end his current relationship with the gf and make an honest woman of TS, then a relationship is given a chance, it's up to them to sustain it. if the pilot intends to keep both girls and TS is ok with this, then pilot and TS deserve each other.
