I have reason to believe that it is quite the contrary. I feel that I can prove that Eren actually loves Mikasa. Even in a romantic way.
In chapter 120 Eren reveals to Ziek that he "only went along with (him)" to get to Ymir and that he "would never partake in such a joke of a plan".
This clearly means he purposely hurt Mikasa and Armin in order to push them away especially because he knew that Mikasa would try to protect him and get herself in trouble by doing so this time. He didn't want to reveal his plans to anyone and kept everythjng to himself which is actually typical of Eren who has always wanted to be the 'lone wolf' independent kind of hero.
Now when he gets his head blown off by Gabi's thunder bolt [in chapter 120 again] we get a flashback of memories... As though these are Eren's last thoughts before a supposed death.
Now if you look closely at these memories, you can see many of the people and experiences that influenced Eren's life, including Armin as a kid, Levi, the warriors, Annie, his mother, a few scenes from his childhood, some recruits, the commander... But one striking difference is that the largest image which occupies the most space in his thoughts is the memory of Mikasa looking back at Eren while carrying wood on her back as a child. Her hair flows and leaves are falling all around her. This clearly depicts a soft romantic image of a girl who is not usually very soft and fragile... If Mikasa was just a comrade or motherly figure to him, I believe his memory of her could be depicted in a very different way, for instance of her fighting for him, trying to protect him or at least wearing her gear as a soldier. But instead, we get this soft (fairly large) romantic image of her looking back at him.
That to me my friend, is proof that Eren actually does love Mikasa and not in a brotherly way. Wether he knows it or not, subconsciously the creator believes that the character of Eren is in love with Mikasa, wether he intended to indicate this or not.
Through this manga, I feel that Hajime is showing that although he has no conscious intention of placing these characters together romantically, he is unintentionally and subconsciously exposing Eren's feelings about Mikasa through very hidden messages that perhaps, even he himself did not intend to show.
