Remember Historia herself mentioned how all of them have been cursed from birth when she was mocking Mikasa.
Most likely, the pieces of the next game are set, and the old same play is starting again. As Kruger suggested it. We have the Ackerman, the royal blood, the commoner who became a kinght, the warriors, the brains, everybody is ready to start the play.
And about Kruger again, he mentioned love and then Armin and Mikasa. Is pretty obvious that this time, maybe, there is something else than the duality of the romantic love.
Eren is the envision of this only if he is actually the one seeing the big picture, far from dead sisters (Grisha's big love and bigger regret is Faye; his marriages has been to fullfill his revenge), dead parents (Zeke, Eren himself, Erwin, Manlet, Mikasa, Armin); dead friends (Jean, Reiner, Bert, Annie).
If you guys pay attention about married couples in this story, they seem not to be the answer. Rod and his family and his lover are one example; Grisha and Dina's treatment towards Zeke is another one; Alma, Rod and Historia are even worse; fucking Grisha and Carla is way more tragic knowing Grisha was soon to die and h was probably nurturing Eren to be the next Attack Titan anyway, without given a shit about Carla's positive way to see life. A baby in this context is the pawn of the devil for keep living.
Eren hurrying the situation is because he wants to avoid any of the cycles, and from his point of view there is no room for playing a romantic soap opera, playing house, or the nakama adventure, once he focusses in a selfish relationship, he will lost sight of the big picture and everything will be doomed to be repeated again.
