This sounds really a LOT like my mom... especially scenario #2. I know that her dad did not come onto her in any way shape or form, thankfully, even superficially, but he divorced her mother when she was 9 or 10 and nothing was ever the same after that, and the backing off during puberty thing was very true as well. I can see how she's a mix of both personality disorders. She has always always always acted out like a clownish, grandiose, barbie doll moron for attention from guy after guy, especially weird guys, who she could use, and she just throws away or pushes aside things that inconvenience her all the time. It's all about her, and she manipulates others all the time and loves breaking up healthy relationships. What is most sickening about her is how much she loves AND hates herself at the same time, and even says disgusting things like 'I'm asexual now'. I've never met a worse, and more pointless human being before, quite honestly. I'm usually very patient and loving but you get to a point where you can't take the weird **** anymore.
