Review Detail of Nob7 in Harry Potter: Dimensional Wizard

It's a good fic but I warn anyone who love James Potter in Hp, I seriously don't understand why the author hate him so much.. I will tell you what happen to him, I'll try to not tell you too much spoilers.Basically it goes like this, Lily Potter (Mother of Harry Potter) get revive by Mc, James Potter (Her husband) didn't get revive with her because Snape told Mc not to revive him.Snape and Lily fall in love after some time because she see how much Snape loves her, and she spaned alot of time with him.. then she and Harry finally can revive James but he see that Snape and his wife are toghter soo he dosen't like that but Lily get mad at him and ask him 'Were have he been all this time?' (Dead)..She and Snape want to marry, she finally remember she have a husband and go tell him that she and Snape want to marry, he get angry, Harry (Lily and James Son), is with his Mother and ask James 'Were he had been all his Childhood, and that Snape was more of a father to him', and that's all I remember..I currently re-reading this fic so I don't really remember what had happen but I remember this because I wanted to drop cuz of this but I didn't cuz I didnt really knew who James was in Hp..Author really did dirty to him, and I want to ask hin why?, because this is seriously one of the worst thing of this fic..All in all, a great fic, this is the only thing that is bad about it, can anyone tell me if James Potter deserves what had happen to him, and what kind of man he is in Hp, please!?!
