Am I like the only like who likes Ugetsu? I don't hate him one bit and I can't hate him ev...

You're not alone. His and Aki's relationship is mess because of both of them. They are both responsible for became of their relationship because neither of them could relinquish the other and thus they both are responsible for the outcome. I like Ugetsu because he is honest with himself about his inability to fully love another and he is tortured by this because he knows Aki needs to move on yet Ugetsu is unable to pull away from Aki in order to end it himself.

As a self-destructive person who has struggled with co-dependency issues and has been in similarly dysfunctional relationships, I relate to both Ugetsu and Aki very much.
