You shouldn't expect your ex to stick around.
Bill is distraught because his wife, Marge, has told him that she is no longer happy, and she wants a divorce.
Bill wants to save his marriage.
Bill asks Marge if there is anything he can do to save their relationship before their divorce is final and, if not, can he save their frienship?
Bill tells Marge that it is immoral, unethical and sacrilegious for a married couple to split up, and that she just can't do that.
Marge tells him that the marriage can't be salvaged but that she would be happy to maintain a friendship with him in the future.
Marge stops talking to Bill completely, because he is being unreasonable, and is only willing to communicate with him through her attorney.
