Matthew is currently in love with Sarah Love, and they seem to have been sweethearts for quite a long time, as seen by his biography. However, he is unaware that Jessie Pilferson has a crush on him. Despite being in love with Sarah Love, neither of them have any memories of each other when first played. There are several other Sims with the surname "Hart" throughout the series, including Randy Hart from SimValley, Sam Hart from Belladonna Cove and the Hart family of Sunset Valley. However, there is no evidence that he is related to any of them.
