As intense as emotions and hormones run, being a teen is difficult enough. Liberty is still getting used to having a Dad in her life. Parker has seen all the ups and downs with Jack and Carly etc. That said, I do like them as a couple, but at their ages, they still have a lot of growing up to do. Yes, I believe that true love can happen, witness Holden & Lily, but it's a huge challenge at any age. Since Liberty doesn't seem to have experienced a lot of adult HEALTHY relationships (her allusions to Janet's obsessing over guy after guy), no wonder she's a bit skeptical and opting for denial...
