It really makes no sense why he wouldn't lift it if he could, they gave absolutely no indication that he just did not to lift it to avoid hurting Thors feelings.
And no, he doesn't have to keep trying, everyone else gave up outside of IM and War Machince who kept trying, hell Black Widow didn't even bother trying.
That scene also served the purpose to make Vision lifting Mjolnir a bigger impact in the film.
