Katrina and Ben:
The relationship between Katrina and Ben is explosive as they keep saying they're friends but they're constantly snipping at each other. each one seems to be trying to get the upper hand by retaliating on points that are really not important. For example Ben stated "some things never change" and Katrina came back with "May you find your future wife at the strip club, your mom will be so proud of you." He comes back to her and says "I'm not looking for a future wife" She replies "I'm not looking for a future husband." They're irritated with each other, but I feel they still love each other and may have some attachment issues.
Hardy and Trixia:
Their relationship doesn't seem to be one of sharing and giving to each other. One of the main issues is Trixia wanting to have a baby as she feels she's getting older and may be running out of time. Hardy feels that having a child would make him feel trapped. People who love each other and want to spend a lifetime together would normally want children. Trixia wants a child for the wrong reason and Hardy doesn't want a child also for the wrong reason. In my opinion they're the wrong people for each other. In order for them to succeed there has to be a major change in attitude and thinking for the both of them or find some one else. The main thing in a relationship other than sex is the ability to be unselfish and sharing.
