Of course, the most glaring thing here is this: Liz is still a terrible communicator, and too immature for any romantic relationship, let alone a long-distance one. She doesn't tell Warren how disappointed she is. She doesn't bring up any concerns that the distance might make their relationship unworkable. She just lies through her teeth and plays the sweet, pleasant doormat, modeling herself after Dee.
And then she has a tantrum worthy of Merrie and/or Robin.
I've said it a million times, and now I'll say it in an OP: Liz does not deserve anyone better than Anthony. I hope they get together and suffer for eternity, locked in a passive-aggressive hell of their own making. The people who deserve better are Francie and the other two kids Liz and Anthony will inevitably spawn together.
P.S.--Wonder how Mike and Dee feel about Liz spraying gallons of spit all over the place? 'Cause, eew.
