This thread is quite interesting. All the thread below explains very well why Brandon can love Marianne, as the novel gives few hints (all said by now) about why he loves her, and why itīs not impossible for a man like him to love a young woman like her. Itīs just that the good things that are said about her are not shown in the action of the novel, that just shows so far her faults. Honestly, at this stage of the book I need a reminder of why he can be loved by him.

I think disliking Marianne is a problem (problem? not really. Letīs call it result. Is a result caused by rereading. In my first read I was 19 and didnīt know where the plot was heading, and I felt identified with Marianne. Later, Iīve always felt much more sympathetic for Brandon. Maybe is an age thing, but I see her under a completely different light. Iīm almost unable to sympathize, and I feel annoyed with her behaviour with people whose only sin is to care for her.
Maybe this thread should be a stable section in the board called:
"Reminder re: Marianneīs worthiness to be loved" or something of the kind. ; P
