Nope that would be Jump Man's. In all honesty though Pauline is a bit weird. You could think Jump Man and Pauline had a son and that ended being Mario (and then Luigi afterwards), or Mario moved to the Mushroom Kingdom and found a new love interest or whatever. I'd like to think Nintendo just wanted to ditch Pauline because she felt like a stereotype unless DK (Cranky Kong) was involved for historical reasons, personally.
peach would never fall in love with bowser. she doesn't even want to stay at bowser's castle! bowser kidnaps her and mario saves her, they kiss each other or something and bowser explose the end. but it's true that bowser has a crush on peach
It's not that Peach might betray Bowser that he kidnaps her, it's because he wants to take over the Mushroom Kingdom and put its citizens under his spells.
The only scenario of Peach going along with Bowser would be the fake "Robot Princess" that he created while the real Princess was on vacation in an episode of The Adventures of Super Mario Bros. 3. (Even at that, when the Princess came back, she defeated the Robot Princess.) Another such possibility would be her falling for Bowser's trap of handing over his castle to her in another episode of that same series.
