Well first I would like to point out that I feel the the "Love" theme in FFVIII is not so much about romantic love as much as personal love. Since VIII's plot is really about Squall finally learning to open up and accept others and himself.

VII sorta've has a complicated love story but ends once Aerith is killed. Cloud has a childhood crush on Tifa and started to have feelings for Aerith but this may be due to his exposure to Jenova cells and Zack and may not have been his personal feelings. Throw in the fact that before he even begins to truly decide how he really feels about her, she's killed and becomes more of an "ideal" than a real person in his mind (isn't it funny what time and insanity does to your memories). Tifa never really gave a damn about Cloud until FFVII really started and Aerith only liked Cloud cause he reminded her of Zack. In essense, the love between Cloud and Aerith is purely fictional within this context. But this is due mostly to my take of the bull they call writing in FFVII, so feel free to ignore.

Honestly, if you want a complicated love story, play Xenogears... Elly and Fei... Lacan, Krelian, and Sophia... Elly and Kim... Elly and Abel... Seriously, this games love story has destroyed all other JRPG love stories for me. Xenosaga may have pulled off something similiar with Jr., MOMO, Sakura, and Albedo but never really went anywhere with it.:rolleyes2
