Me and my bf have had lately relationship problems. I was only not long ago to find out he has depression.

We live together abroad away from our families and friends. I have more friends here than him, he is feeling kinda lonely I guess which contributed to him developing depression.

When he drinks he used to be angry and yell at me but next morning apologizes and tells me he has anger issues.

I usually find out things about him during arguments, and he yells at me and says his nerves are not ok. He is not excluding option to search help but haven't done yet.

I love him a lot and I want him to be ok, but I'm not sure if this is the depression or he no longer has feelings for me?

For example, he would be excited to meet his friend once in a while (the only one he has actually) but not go anywhere with me: coffees, bar, cinemas, he just wants to stay home if I'm in the story, he makes up excuses that he is tired and stuff ..

Tl;dr I see Mt bf battling depression everyday as his moods really shift within hours.  Is this something I should keep up and help him get through or he is no longer interested in me? Advices appreciated and ways how to cope with it.
