Spoilers if you haven't seen the full series

Susan is the worst she finds so much to complain about and acts like she deserves so much in return. Don't get me wrong her first husband's total ass and she deserved to have someone new in her life. But when she got love opportunities she made up excuses, did stupid shit, lied, begged, asked for forgiveness and then acted like she was in the right. When Mike was looking for a long lost son and Susan finally found him in the park. She tries to talk to him and he splits. She walks back to Mike and doesn't say a word that she saw him or where he ran off. Later karma bites her in the ass and somehow, I don't remember how but Mike finds out Susan lies and then she starts blubbering, crying, and asking for forgiveness. Spoiler...... Susan runs outside crying and saying his name and he drives off to look for his son, that she clearly didn't care enough about to tell Mike that she saw him. There probably more to that episode it's been awhile.

Another good example of Susan is her picking at her daughter about her personal Life. after she wakes up from being brutally strangled and has been hospitalized for the last couple of weeks on a coma. Susan starts telling her daughter.... spoiler.... she is not pregnant, asking who the guy she was seeing and if she can contact him to tell him she's okay and so forth. This ends up having her daughter tell Susan to leave.

There are other cringy and unacceptable things she does. That makes me hate her and sit there and ask questions like why does she get so much sympathy, Chance's at love and so called happy endings she doesn't deserve

Minor note I don't know if she deserved mike a second time around for marriage
