Honestly after just watching it, I say Cloud is not with anyone. The entire movie he can't forgive himself for letting Aeris die, just because he feels the need to protect EVERYONE. *SPOILER* When Sephiroth has the Masamune in his shoulder he asks if there was anything he could have the pleasure of taking away from him, and cloud says "How pitiful. You don't understand anything at all. There is nothing that isn't important to me." Cloud is fighting for everyone and everything, he is not directly connected or in love with one person. He feels obligated to protect everyone and everything. It's like the opposite of the Matrix... in the matrix Neo is completely in love with Trinity, but as the architect said, the previous "ones" had been in love with the human race as a whole and did what they saw best for everyone, while Neo fought for one person. Cloud wasn't fighting for one person, he was fighting for everyone. I don't see love for Tifa, except maybe the shared love they have for the children and their strong friendship which he has with all the characters from the game. I don't see love for Aeris, just terrible regret that he had not done more to save her, and needed her forgiveness, when he realized it wasn't really his fault with her help and stuff, and that she was really still there, he was able to move on and get new strength and fight.

In conclusion, Cloud is in love with everything and wants to protect everyone and everything, he's not in love with either Tifa or Aeris. Even Tifa said "we're not a real family." They're together at the orphanage because they both love the children and want to protect them.
