you're the worst kind of person.

What your friend didn't mention a trip to Japan to him either? And he decided to get engaged to you without even breaking it off with her? And when he saw you coming off the plane he didn't notice his girlfriend right next to you? FAIL

no offense, but why would you put something like that on this website? have you seen how many FML's are about people being cheated on? no one's feeling sorry for you. it serves you right. and if she's your BEST friend, i dont want to know how you treat your regular friends. im trying to go about this as nicely as i can, but you dont treat your best friends that way. if she was your best friend, then you'd suck up the fact that you had feelings for him and get on with your life. i feel sorry that you made the decision, but im not sorry about its consequences. im basically just sorry that you were daft enough to do it in the first place. but i do have a few pressing questions. [i havent read all of the other 150+ comments on here, so i dont know if this has been answered yet.] how long had the affair been going on? IF she wasnt with you and he asked, would you have said yes? also, if you did say yes, how would you tell your best friend? i have a few more, but i'll leave it at that. if you prefer not to comment, im okay with that as well. i respect that. for other people commenting, i dont want to start a riot or something, but i would like to point out one thing. this girl, the one who posted this, has yet to have commented anyone back. on this message board, that is. so theres no telling why she did it or how she kept it under her friends nose the whole time. it happened. it was bad. but if she wants to talk more, she will do so. but after a bit, i think she's really realized that she's made a bad mistake and that she probably will not be able to patch their friendship up again. that is all.

you are a huge bitch

You're a ******* bitch.

What makes you think you're the first girl he's cheated with that he has proposed to? There could be a third girl with a ring on her finger also, and you're all just getting played. Once a cheater, always a cheater. Whatever is coming your way, you deserve.

I quite disagree, #170, not every guy has the guts to those stuff all the the time, even if he is a cheater... And, damn... Why the hell people submit those stories expecting pity and compreension? You deserve it, ****.

Hah! I thought that "my husband sucked my crush's dick and now I hate them both" would have the best shot of the recent crop to hit the #1 flop FML. This just surpassed it.

You're a shitty best friend.

Just figured I'd drive the "you're a ****" sentiment home.

Wow - major damage! Post #17 suggests at least one reasonable possibility, but lots of people seem unconvinced. So let's take what we have been told, and see if there is are any other reasonable ways for that to be true... Let's guess that OP, her "best friend" (for want of a better term), and the alleged boyfriend all grew up in the same area. Let's further guess that "best friend" has moved away for a time - perhaps to college interstate. So OP has been enjoying spending time and exchanging bodily fluids with alleged boyfriend. Then OP decides to go to Japan - lord know why. In her infinite wisdom (for want of a better term) OP decides not to tell alleged boyfriend that "best friend" is going with her to Japan. Now for this to make any sense, OP must know that it is very unlikely that alleged boyfriend will hear from "best friend" about the trip. Perhaps because the trip was at short notice - or at least that "best friend's" coming along too was. Perhaps "best friend" was joining OP on the trip because she needed some time with her "best friend" (OP) to talk about her suspicions that her alleged boyfriend is cheating on her? Who knows? So OP and "best friend" arrive back and apparently go to grab some food at the airport. Why? Perhaps because "best friend" is connecting with a domestic flight to wherever she is living/going to college. So OP believes that her world is rosy. She's been having a great time (and sex) while her "best friend" is away, and has also got to spend some great time *with* her "best friend" - which probably would not have been the case if "best friend" had known about the affair with the alleged boyfriend. So alleged boyfriend turns up at the airport to propose - thus ruining the perfect setup that OP has going. So how did it come to be that this all happened in front of "best friend"? Perhaps alleged boyfriend was there at the airport with a huge sign saying "CoolGirl I love you - marry me!" Perhaps he was so focussed on running up to OP, putting his hand up her skirt and proposing that he failed to notice "best friend" coming up behind her and stopping next to her. Perhaps alleged boyfriend is the biggest, most insensitive turd on the whole planet and proposed to OP even though "best friend" was plainly there. My guess is that OP posted this as an FML because she feels that idiot boyfriend has stuffed up her friendship with "best friend". It seems quite likely that OP had no intentions of marrying alleged boyfriend - just hooking up with him when "best friend" is not around. Note that I'm not condoning OP - I'm just suggesting what I think is a plausible scenario in which this whole post could reasonably be true. All the other posts here have done an admirable job of expressing their views on OP's moral compass (for want of a better term), and perspective on who might have been injured most by the events.

You deserved that you jerk face!!!!
