<human>: Can you provide a brief rundown of the text in within 3 sentences?

My closest friend and roommate (f21) is incredibly codependent, and aware of it. She struggled with self esteem and feeling guilty when she doesn't allow herself to be manipulated. My main concern for her is her relationship with this guy.

She met Jack about 2 years ago and immediately liked him. He was everything she thought she wanted- suave, "cool", confident. Having known this guy for equally as long, I can tell you he is 100% a douche. He is a salesman by nature, manipulative and coy.

She had a brief sexual relationship with Jack, who soon after admitted he didn't have feelings for her and it was just a fling. This is very much like him. She, however, was hooked. Soon after he got a girlfriend, whom he has been dating and partially living with for a year.

My roommate spends inordinate amounts of time with him, smoking, driving him places, buying him food. She can't let go and refuses to, even though it's obvious to the people around her that she needs to separate herself from this jackass. He likes getting rides and meals and *attention* from her. He is a narcissist.

I have been patient, loving, trying to bring her closer to being okay with letting go of Jack and moving on, but she continues to abandon plans with me and others to go spend time with this man that has absolutely NO interest in her whatsoever.

About 6 months ago Jack told me he uses her for her car, and she makes him feel good about himself. I tried to let my roommate know but she believes in Jack.

How can I help her? Buy her Codependent No More? Drag her to a coda meeting? Talk to Jack?

It's beyond frustrating.
<bot>: Codependent roommate attached to a man that couldn't give a shit about her. Does favors and spends money on him and ditches other friends to do so. How to help her let go of this toxic attraction?
