Hello everyone, it is my first post, just registered.. I really need some advice.

I'm in +9 years relationship and most of it has gone by lovely. But starting from two years ago, after a traumatic event, my partner has been suffering from panic attacks and what I believe to be depression (he refuses to have therapy so I do not really know). Economical crisis has forced us to move country in the hopes of reaching more stability. I took up the occasion to go back to university. He is in a very precarious situation, as he doesn't know the local language. He has managed to find a job amongst fellow expats but as a previous small business owner he absolutely hates it, not being in control and also working in a field which isn't where his passion lies. This has all been very difficult for him, and I can't stress enough how much I both admire him and am feeling I am failing him, as I want him to feel better I try and distract him and make him appreciate the small things we do have going for us. Nothing seems to work though and it is stressful for me also, and difficult not to let his mindset contage me. Spending time with him is a constant effort to get him to enjoy something, and I often now get anxious and feel down when I'm with him. Sometimes (more or less once every 3 weeks) I go out with the acquaintances I made at the university, which always lifts my spirits because it's a moment where I don't have to worry all the time and just enjoy. I tried to introduce my partner to the group but this went less than well, for obvious language problems but also a lack of attention from the group for the newcomer. My partner now has a distinct hatred for these people (especially the one male member of the group) and discourages me from seeing them (always especially mentioning that one guy), saying that if the tables had been turned, he would never continue seeing someone that would have treated me in that manner. So now every time I go out it becomes a terrible issue and I don't know how to handle it. Yesterday I went out with this group to watch a movie, got home before eleven and had to listen to my partner saying things like "it's obvious you don't care about me since you haven't called me during the evening, what were you doing that was so important? Don't the petty teachers allow you to use your cell? Or were you all doing a nice little orgy?" I just shut down and couldn't respond a single word. I feel terrible and I don't know what to do. I don't want to cut myself off from the few people I managed to get to know and like, but I realise this whole situation is extremely stressful to my partner and I don't want to worsten his situation either. I've already cut down the time I spend with them but it never seems to be enough. Any advice?
