I will say, for a lot of relationships Bart has had, some of them could easily have remained as friends similar to Laura. Mainly Mary, Greta & maybe Gina. Nikki & Jessica I'm not sure, and Jenny I can see hating Bart for lying to her.
TheRealJims just released what is, quite possibly, the most succinct, thorough and observant breakdown of Bart's many romantic trysts and forays and what they ultimately say about his character.
I honestly think it's one of his best written videos to date.
