In season 3, Mat is to leave to go on a three week band tour.

Later in Idyllwild, they get back together after he returns from tour and tells her how much she means to him. When alone together, he admits how the real reason he turned down her offer to have sex was because he is also a virgin and wanted them to lose their virginity together.

Matt is a member of Brandon's band. This is how Mariana originally got to know him. The two initially bantered often, and as the two grew close. Matt, after asking for Brandon's permission, asked her out, to which she accepted. The two connected over having biological parents abandoning them and the uncomfortableness of letting someone know. Things are going good with them until Mat informs Mariana that his band, Someone's Little Sister, is going on tour for three weeks in the beginning of the summer. Upset that he'll be gone for so long, she initially pushes him away, before they talk it out, and Mat and Mariana then say "I love you" for the first time in Light of Day. Mariana plans on having sex with Mat in Wreckage before he goes on his tour, so he has something to remember her by. Mat rejects her, however, wanting their first time to be somewhere special. After he leaves her, Mariana, believing he rejected her so he can have sex with other girls on tour, drinks and has sex with Wyatt. She immediately regrets the decision.
They break up in More Than Words after Mat drives back down to visit Mariana. He apologizes for leaving her like he did, and says that he'd like to have sex with her while he's back, if she still wants to. Mariana, unable to handle the guilt of cheating on him with Wyatt, which Mat was unaware of, and knowing Mat would be spending a large amount of time away on tour, breaks up with Mat. They briefly re-unite in Idyllwild following Brandon's music performance, with Mat claiming that he'll give up the tour to spend the summer with her if it wasn't too late. However, when Mat admits the reason he rejected her the first time was because he was a virgin too and wished for them to lose their virginity together somewhere special, Mariana admits in shame that she had sex with another guy. Mat, heartbroken, refuses to talk to her for some time. In Lucky, in an effort to win him back, Mariana sings a love song to him, but Mat walks away mid performance. Mariana finally confronts him after the performance by saying she knows she made a huge mistake, but has forgiven herself. When Mat says he is glad to hear that, Mariana hopes this means they can date again. However, Mat tells her that while he is glad she has forgiven herself, he is not willing to get back together, and leaves the room, leaving behind a dejected and hurt Mariana.
Mat and Mariana are both later cast as Romeo and Juliet in Mat and Brandon's senior project, R+J. Throughout rehearsing for the show, the two date other people, but are still shown to have feelings for one another. Come opening night, their feelings come to a head and they finally tell each other they still love one another in The Show. Mat had initially left Mariana a letter about it, and how he has forgiven her for the Wyatt incident, but she never got it because her boyfriend, Nick, had intercepted it and destroyed it. They decided to not pursue a relationship initially, because they both didn't want to hurt their significant others. However, after Nick comes to school and then her house with a gun, Mariana's relationship with him effectively ends, and she and Mat get back together in Trust.
Their relationship gets rocky once Mat finds out that Mariana had still been seeing Nick and allowing Nick to believe they were still together, even after she got back together with Mat, and also when he found out about her taking her brother's Adderall medication. She soothes his doubts and questions when he confronts her in Dream a Little Dream, and the two end up having sex. But after some questioning from Brandon to Mat on the possibility of Mariana being pregnant, after witnessing Emma buy a pregnancy test and hand the bag off to Mariana, Mat realized that he couldn't trust Mariana again after all the lying she's done to him, and they break up in Cruel and Unusual.
