Losing faith in my PhD advisor?
but found out later that all his approaches to the problem just don't "hit" the point


...


  I guessed he hate me for that and trying to stall my work


...


  Any risk that he will rant me to the co-supervisor?


...


  I just had that bad feeling about the project he led and many of his direction doesn't make sense to me. Doing his way or my way is doomed anyway. 


There is only one suggestion that we can give you. Get out of there. There is no telling whether his research is indeed "doomed", or whether you just have different angles of attack and ideas. In the end, it does not matter. You have no respect in his guidance and will need to find an advisor whose advise you actually trust.
