I am currently doing a Master by Research. I started two months ago,and it has taken me a while to get used to being here. The things is, at the beginning my supervisor was really nice to me, he was constantly asking how I was doing and helping me with any worry I had, and this helped me a lot because I am a foreign student and I was feeling pretty lonely at that time. But now, I feel like he has lost all interest, I mean, he stills asks me how I'm doing if we meet in the hallway or in lab, and we have meetings anytime I tell him I'm done with what I was doing, but if I didn't ask or go to his desk I feel like he wouldn't even notice I'm here. Since is my first approach to research I was wondering if he's doing a normal/good job or if he should be more interested? Is a supervisor supposed to care just for professional things? I'm feeling really down and I really would like to talk to him, but I feel like I just should approach for professional matters.
