Aibu that It should've been Rebecca and Nathaniel in the end.
(The show 'Crazy ex girlfriend' for anyone who doesn't know)
Josh caused her so much pain, he slept with her at camp even though he was with Valencia, he treated Valencia like crap and Rebecca at the same time, he moved in with her when he broke up with Valencia and treat her like a motel.
He proposed on a whim and left her at the alter.
They never made sense as a couple. At all.
Greg the alcoholic who was obsessed with her then went cold when he got her, got so drunk and abandoned her at the wedding for months. Ran off for 2 years, they got back together but he could even muster an ounce of happiness for her so they split again.
They were a terrible couple.
Nathaniel did everything for her. They only broke up because she felt herself becoming obsessive with him, it was always her bpd that stopped her. He changed and became a lovely and kind man and never wavered with telling her he loved her.
