Reader with a Cause discussion

From the Commitment Ceremony one week to "manhandling" her the next, what do you think about Lula & Evan's relationship dynamic? Do you think Duffield's volatile nature is a result of his drug use and life in the spotlight (which is still no excuse for “manhandling” your significant other), or is something else at play?

"...she [Lula] and Evan go back together and they had the commitment ceremony; it was all fantastic for her, she was on cloud nine." -Ciara (320)

"'Then Duffield and Lula argued. Lots of people saw it happen. He manhandled her a bit, tried to make her stay, but she left the club alone.'" (35)

"Well, yeah. I saw her number coming up...I felt like teaching her a little lesson. Let her wonder what I was up to..." (340)

"[Lula] got up, came over to tell me she was leaving, and said I could have my bangle back; the one I gave her when we had our commitment ceremony. She chucked it down on the table in front of me, with everyone fucking gawping. So I picked it up and said, 'Anyone fancy this, it's going spare?'" -Evan (342)
