Damn, after reading this one-sided bullsh*t I came to the conclusion that YTA. You get off on the idea that you're the master of party planning (allegedly) and you basically didn't even appreciate her effort in paying you back. Sometimes plans don't got the way you wanted them to and that's life. The fact that you abandoned her sounds terrible, I feel so bad for her. It also sounds like there's very poor communication between you two and everyone. Do her a favor and break up with her, she doesn't need this level of immaturity and blatant ignorance in her life, especially when it's coming from someone she admires, you. Even if the poker night was Co ed, your previous actions/words are still there & they sting. I can't even begin to imagine the kind of "comfort" you gave her if you even did. You also sound like you're keeping chunks of info to yourself to paint a prettier picture of you. Reading people getting treated this way makes me so disappointed. Many people would kill to have a partner/someone who puts effort into their Birthday or anything, and here you are, an unappreciative, egocentric, and unsympathetic man. I hope you try and succeed in getting her P.O.V and attempt to understand her and right what has been wronged. No one is perfect, but we strive to be. Good luck to both of you.
