Imagine if you go stead with her then ultimately marry her, then got to endure her mother's ultra nonsensical character till she dies....
Not a deal right? No matter how chio the girl is also is a deal breaker right?
Because you cannot tell the girl to disown her own mother. Neither can you stand long term tolerating her mother's nonsense.
Further, her mother's genes might have passed down to her and in the future, when she grows older, she will become 2.0 version of the monster...
Correct?
