First of all let me explain my situation a little bit.

I am writing my masters thesis in theoretical quantum field theory and have a very bad contact with my promoter. I see him once every few weeks and he doesn't have any concrete feedback. (40 written pages have been laying on his desk for months without any feedback on them) There is one PhD student that is helping me but our ideas are not in line and all he does is giving negative feedback up to the point where I cannot value it anymore (it feels personal instead of professional)

This situation is becoming rather desperate since I was hoping for a PhD in physics but I have no recommendation letters from my promoter which ruins much of my chances...

I have talked to other professors at the faculty and they tell me that that they know him and that it doesn't really amaze him but this does not help me. That same professor might be willing to get me started in a PhD but I am afraid that he'll ask my current promoter how I work and whatever he says it will not be representative of how hard I work.

Last but not least, the deadline for my thesis is in a couple of months and I am yet to get some feedback on a crucial, very onorthodox, step that I made. I motivated the step and anybody asking me will see that I though about for a very long time but still, it might be wrong. Can I get a total fail for my thesis if this is the case? And how does this influence my further carreer ?

I felt really confident at first for a PhD I am very motivated and work a lot, but this whole situation is really taking away my academical drive.

Any tips and advices ?
