oh you are gonna hate me for this reply, but thats ok, i feel like sayin this.....
i think you over reacted!
chicks ARE drama queens... and damn, it was just a chat online...
what if he got pissed cuz you went to pee without him?!
in my experience... guys arent as thrilled about the candles, and chocolates and crap as much as you are....
guys just want to do their duty which is to let you know you are their chick , and they want to get laid.
it sounds like you are demanding his constant attention to be on YOU when really, valentines should be about BOTH of you.... doing things together you both enjoy...
and you gave up on the relationship cuz you didnt get all the attention?!
reminds me of my 6 year old niece... spoiled.
ive done it before.. but i am glad i have been hurt enough by my selfish actions and guys not being able to give me all i wanted... cuz it isnt realistic....

seriously.... try to take a walk in a guy's shoes...
the things they like to do are different than what us chicks want to do.

and maybe just learn to be able to go with the flow. nothing will ever turn out exactly as you plan it in your mind, so you have to be able to deal with little inconveniences as they pop up throughout any special event.
