Regarding getting with the married spongebob, I used to have a 'friend' who did things like this. The men weren't quite married because we were younger but they had long term serious partners or had just broken up. Anyway, she never had a relationship or anything with boys while we were at school and I think as we got older she started to see a guy in a relationship as a sort of challenge. She would almost be on a high if they were interested in her, even if she wasn't interested in them at all. She entertained on guy who had a girlfriend for months and she didn't even like him, but she was incredibly lonely. It was bizarre to witness her behaviour. It's as if she thought that she was somehow in the number 1 spot because this guy had a girlfriend he was cheating on with her
. I feel as though Arianna had that same super low self esteem so in her mind whats better than getting someone who shouldn't want you, to want you. This friend always claimed she didn't owe the girlfriends anything and if the men were going to cheat with her then that's just the type of man that they are. She was very much of the mindset if it's not me then it would be someone else.
I hope spongebobs (ex?)wife is doing okay, that's the type of hurt that changes everything and how you look back on your memories.
