its saying he wants a relationship with this woman he met where he can talk to her and not just party and have sex
he is kind of longing for that moment to return when she was happy to be in his company and not just drunk and screaming
then he says wait we could have more, dont be just another one night stand, but he cant stop the the rhythm of life to be with her
he wants her open up to him
but she just leaves and gets on with her life
he is looking back and saying maybe we could have had something there and regrets not trying to make anything happen
my interpretation arranged stanza by stanza:
