Yes, Eren does love Mikasa as she is definitely the most important woman in his life after his mother. Despite this, it is possible for Eren and Historia to marry — more out of duty and obligation than love.
You should be thinking “Does mikasa and eren get married?”
Long Answer: It is heavily hinted but not really expressed in the story that she does, even though Armin tells Eren that he should tell Mikasa about his feelings before it’s too late and “she falls for someone else” (i. e, Annie). Do eren and mikasa get married.
This of course begs the inquiry “Is Mikasa in love with Eren?”
Mikasa actually loves Eren in a romantic way. It is heavy hinted and implied throughout the series that Milasa loves Eren. There are multiple reasons why she loves Eren. Starting with the back story how these two first mint Eren literally saved her life from becoming a sex slave.
Why did Eren say he hates Mikasa?
Eren accuses Mikasa of blindly following his orders because of her genetics, and he despises this lack of free will. Assuming Eren’s words are honest, his hatred for Mikasa is an extension of his ceaseless determination to end the war between Eldia and Marley by any means necessary.
Your question says “most likely”, so no. Mikasa is not “most likely” to end up with Jean . Because she is madly in love with Eren, she is most likely to end up with Eren! And I believe that Eren likes her back but has not yet realized his feelings.
Who is Eren Yeager girlfriend?
Eren doesn’t have a girlfriend. The show is mostly focused on the story and the events taking place and gives relationships last priority. That’s you answer. Nothing regarding relationship is specific even in the manga.
