probably "indecision" is the wrong term. Josy in those occasions knows what she should do, what it would be right to do, but she always lets herself be carried away by passion. and this often leads her to say "inappropriate" things.
the same behavior on the part of MC is demolished (imagine Mc thinking about his relationship with Jill and then after some doubts having sex with Bella).
but I don't agree with you on the reason, we can't say that he does it for fear of losing them both, that can be worth the limit for the post chapter 4.
but as soon as she knows Mc, what fear can she have of losing him? when at that moment it is she who is about to leave both
we can say that Josy behaves sentimentally like MC the manwhore (not all games but many ..), with the aggravating circumstance that Josy believes / believed in a relationship with Maya. but unlike Mc, she always expresses these doubts in words and not in thoughts
here I think you are wrong.
that is a distinctive trait of Josy's personality that is shown and underlined from the beginning. Josy talks to everyone, gives everyone confidence. when she arrives in BR the first day she already becomes friends with Jill, even with Quinn she doesn't show any fear, she responds blow for blow.
let's say it's not a feature that in real life would drive me crazy, but it's consistent with the way the character was presented to us
