My advisor won't review my papers, and he does not let me publish them without his approval
This seems like a case in which a delegation from your group should ask for an intervention from a higher level. If it is a general problem in your research group then department heads and deans need to be aware of it.
You may not get the feedback you need, other than from each other, but the &quot;permission to publish&quot; needs to get resolved, perhaps as a demand from above.
It might also be possible, depending on the overall organization, for other faculty to intervene on your behalf.
