Hey I saw your picture in Facebook and I want to be your boyfriend if you are still available! Are MSc students welcome as well?

I believe the best thing you can do in a situation like this is to find all the alternatives you have (except from quiting of course) and try to make changes that will make you happy ASAP. If you can change supervisor do it! There is no need to destroy your personality for the sake of someone who has obviously misunderstood the reason why science is great!
I know MSc and undergraduate students that work on research projects for 60+ hours/week. If you do not have time to practise your intellectual skills, take your time to think about your experiments, then there is no chance to become an independent scientist who can make a unique contribution to their field..Think about that!!
