What is the next step?

My bf's Father ped 3months ago and in this time he seems to have sank deeper and deeper into depression and anger. I have been there for him the best I can and suggested that he speak with someone about how he feels and how he can deal with the loss better. Soon after his Father's death a lot of upsetting things were brought to life that mainly dealt with financial irresponsibility's on his Father's part, that has left the family in a huge bind. He's very withdrawn and at times he just wants to be alone and deal with things. He moved away about a month ago to take care of his Mother, but had to leave to get back to work (in a different state that me), so I haven't been able to be there like I want for the last month or so. He hardly calls me anymore and I'm left to do most of the calling just to make sure he's doing alright. The other day he told me that he was very angry at his Father and had questions that he still wished to ask (the whys and other questions people have). He said that that he's going to speak with someone soon and I believe him, but I also fear that our relationship is in jeopardy. I'm not sure if I should keep calling and being there for him or step back and live my life without him. He also says things like "this isn't fair to you"... and "I feel like I'm keeping you from life." Is this normal for people to say who are hurting or should I take heed to what he's saying. He's definitely nowhere near the person he used to be, so full os life and laughter. Now he's just so sad.
