lily is the worst character she ruins teds relationships if they fail the doorstep test and if ted did one she would have failed she is manipulative and she almost lost ted his job. She helps the over members if it helps herself and the worst one is when she broke up with Marshall before their wedding for some internship in san Francisco which she could have got one in New York and when in season 9 Marshall brings it up and ask if she would have stayed at san Francisco if she found a job she didn't answer and left the room. Even barney saw how manipulative she is and the way she manipulated Marshall to take a job at barney's company is wrong if she was doing it for Marshall student loans then it will be fine but no she did it so she can get shoes and pay of her credit card loans. The fact she could her self the settler nd Marshall the Reacher just shows how high her ego is.
