Doesn't she also say that if he finds out exactly what her conditions are, then it will ruin any chance of them getting close, so her conditions are probably to be nice to him then, which makes sense with her sudden turn around after kicking him out and the nasty phone call, messages, emails etc.
Bella said that after the will reading Elaine was very troubled, was that because she had to suddenly be nice to him to get her share and she had just kicked him out, the father also mentioned in his message to the mc that he thought she would kick him straight out, is he pitting them against each other, having kept her from being nice to him for years, then dropping a bombshell that she now has to do the opposite or she gets nothing, also knowing the mc will not believe her sudden change of heart.
