Oh wow, i see her completly different. Imo she never "not accepted" to have feelings for the MC, i mean she wears the wedding ring again early, has the wedding picture at the wall in her house years after the divorce.
Imo Allie's problem is the opposite, she is conflicted because she is fully aware that she never was able to stop having feelings for the MC but "forces"/expects herself to hate him. Her being still in love with him is the main reason why she stayed this angry the whole time.
She didnt suddenly realised "oh fuck, i still love him", imo its more like a "why do i still love this asshole?!" since the first time she appeared in this avn.

Do you consider that not sexy?
