its odd to me that you guys went out for drinks then came back to your place till 3 am drinking even more and nothing happend.
it sounds like you are ready for step E - Engage Physically. it's important that you follow this up by Nurturing dependence, and then Neglecting her emotionally
This! Except don't call her. Wait for her after work, or find a way to see her in person and walk up to her and say it to her face. Watch her blush and giggle. Then keep pouring it on.
The easy answer: she came to her senses, realized you are an AFC (average frustrated chump) and has cut her losses. Move on. Go plow some other fields, sow oats, but don't ever call her or text her again. Then she will see that you for the desperate dude you are. Get over it.
Text her the following: What's better than a rose on my piano? When she asks what, respond: Tulips on my organ.
This guy is the opposite of houstunnin. Asks for help and then gives no response. Mizhemp, I'd like to give you some advice face to face. I know a good tapioca place. I'll be in a beat up Accord (no a/c).
