The two were rivals for parental attention and success, and Melissa often won the fight, which angered Spencer. The sisters' iterations broke up after a traumatic memory loss Spencer had in their childhood. An armed robber accosted the family during an outing and Spencer, having lost all memory of the experience, was never the same since that day. Their parents apparently worried about her so much that Melissa had to miss several competitions that year. Thus, the rivalry for their parents' attention began.

The not-knowing of his whereabouts in the night Alison disappeared jeopardized their relationship. Wren Kingston: Melissa's second serious boyfriend and eventually fiancée. They were planning to move in to the townhouse her parents purchased. While Melissa seemed to love him, Wren didn't seem to feel the same level of affection, which caused him to prefer and kiss Spencer and jeopardize his engagement with Melissa. However, he eventually hooked up again with Melissa, who eventually made sure that he would be out of both of their lives for good. Wren and Spencer later started dating again, with Melissa's blessing. Jason DiLaurentis: The two had a brief casual relationship in which Melissa didn't care for him the way he did for her. As a way to get closer, Ian revealed to Melissa the secret about the DiLaurentis twins and asked for her to keep it a secret between them, which she did. Darren Wilden: Shortly after the fire in the Poconos house, Melissa and Wilden started dating and eventually he proposed to her. Spencer likes Melissa's relationship with Wilden, which strengthened their sister bond.
