- "We're not perfect, Michael. But at least we're both trying. It'll take some time, but we'll be okay."
- ―Amanda De Santa
Amanda was working as a stripper and possibly a prostitute (according to Trevor and as implied by her son) when she first met Michael Townley. Her history before that is unknown minus that when Michael first met her she was living in a trailer park in the Midwest. The relationship between Amanda and Michael has become very sour over the last decade and they barely tolerate each other. Michael spends his time drinking, moping, and losing his temper at her. She spends his money freely on expensive clothing, jewelry, and plastic surgery, while verbally abusing him. They have two children together, Jimmy and Tracey.

She later appears in the mission Complications, while Franklin is invading Michael's House to retrive Jimmy's BeeJay XL.

- ―Amanda, before leaving Michael.
During the mission Did Somebody Say Yoga?, Michael and Amanda are having another argument, this time about Trevor's return. When Fabien LaRouche, Amanda's yoga teacher, arrives and invite both of them to a yoga session, Michael agrees to try a class, much to Amanda's frustration. The session is going well, until Fabien attempts to Amanda into an inappropriate yoga position. This causes Michael to lash out and attempt to punch Fabien, but he misses and falls in the pool. Amanda gets angry with Michael's constant angry behavior and leaves him, takes the children and moves in with Fabien.
While Amanda is gone, she tries to make Michael jealous, by leaving posts on his Lifeinvader page, saying that Fabien satisfies her physically, emotionally and spiritually. However, after some time, she will show that she still worrys about her husband. She will call Franklin after the mission Minor Turbulence, asking if Michael is still alive and let a message in his Lifeinvader page saying to him let her know that he is ok.
- "Listen, Michael, I'm so glad we're back together and making a go of things. After everything we've been through, I just couldn't give up on our family. Yes, you're awful and clearly you're never going to change, but I guess I want to bury you, when the time comes, as your wife."
- ―Amanda, in an e-mail send to Michael after the mission Reuniting the Family.
After a few weeks, in the mission Reuniting the Family, Jimmy finally visits the house to check up on Michael. He claims that Amanda is not happy with Fabien any longer, and that she is at a Bean Machine café with him. The two then leave to go pick up Tracey, and later show up at Bean Machine. Fabien is shown verbally abusing Amanda, and the two are then surprised to see Michael. Fabien then insults both Michael and Jimmy and Amanda turns on him, calmly asking Michael to hit him. Michael then grabs a laptop and bashes it over Fabien's head, nearly knocking him out. Satisfied, Amanda tells Michael to take himself and the children to Dr. Friedlander's therapy office, then drives off to take Fabien to the E.R. During the therapy session, the couple vent and argue at each other, but by the end they are both satisfied by the release of anger. They both promise to try and make each other happy and no longer cheat on each other, and Amanda and the children move back in.
Later, in the mission Meltdown, she and Tracey are made hostages by Merry Weather soldiers that attacked Michael's house in retaliation of Michael's betrayal of Devin Weston. Michael kills all the Merryweather soldiers and save his family. But Amanda, Jimmy and Tracey once again leaves the mansion, this time to lay low while Devin is still trying to kill Michael.

- ―Amanda about the future of her relationship with Michael.
