Well, personally. I'm pretty much going to heavily disagree with your idea of Eddie not having a 'unattachment to romance'. In game he was HEAVILY attached to Ophelia, his whole story line with her is a romance. One that hits a lot of bumps in the road. To say he has no attachment is kind of not understanding Eddie or the game's storyline. Eddie has full capabilities to have a romantic relationship, he is just a very awkward, cocky douchebag who does dumb shit on a regular basis. When he loves someone, he loves them very deeply, but still makes dumb mistakes and hurts them without meaning to. This is clear from Brutal Legend's in game storyline where he left Ophelia behind due to a misunderstanding.

He may have fought with her due to the drowning doom, but he was STILL very much in love with her. His reaction to her death at the end of Brutal Legend is a clear idea that he was still in love with her and knew he made a terrible bad mistake. In game dialogue, amongst his cocky behavior and comments, he still has a lot of love for Ophelia. He fell out of love with her in fac from being parted from her for such a long time and parting on very, very rocky terms. I pulled him mid-fight with her, he spent a year or so idling at fac. This time let him grow as a character and figure out he can love outside of what he had done before.
