What about this...your drunken T was going to drive drunk, thus exhibiting dangerous, irresponsible behavior. You were ok with letting that happen.

In real life, your T exhibited dangerous, irresponsible behavior in how she handled things with you. Do you now find yourself starting to be ok with moving on from that? Maybe the dream is showing you that you are letting go of the stupid stuff your T did to you and moving on. So perhaps this dream is a sign of resolution, forgiveness and healing. Or, maybe it's just a sign that your T likes to party. Hahaa!
