I just watched this for the first time and....
where we supposed to feel sorry for Maureen? She went after a boy she knew her sister really, really liked. Went on 1 date, had sex, and she fell so head over heals for him that even their parents were on her side.
I'm just going by the timeline of their mother's pregnancy, but she had to have been all of 8 months already at the beginning of the movie, so I'm guessing that 2 or 3 months had passed....and the majority of that time was spent on Court and Dani.
I guess I really didn't really like the scene with Dani and her dad when they were fishing and he basically told her to "suck it up" and that your sister is hurting worse than you.
