So frustrated.

So Mike (my boyfriend) is taking the day to himself. Says he just needs to be alone today. I'm trying so hard to understand and be okay with that. But I'm so worried about him, I can't help it. And I want to be there for him, so badly. I know he's not okay. He will admit that much. And I know why and what's going on....but there is not a damn thing I can do about it to help him and that kills me. I do my best to be supportive and helpful, and I know he knows I'm here for him...but he is the type to not want to talk about things and such. But honestly, if he doesn't do something about the whole situation he is in, it's not going to get much better. But I can't tell him that. It's like WW3 when I try. And it's seriously taking a toll on our relationship and on me personally. God I hate to admit that because it makes me feel so selfish. But it is all getting to me. He's always in a bad mood and sometimes it's like I can't even talk to him anymore. He gets upset and/or mad so easily now. He always apologizes and always insists that none of it is my fault, but sometimes I can't help but blame myself anyways. How can I not? And he doesn't get that concept. He seems to think I should just always know it isn't. But it's not that easy. I honestly really wish it was. I wish things could just go back to the way they were.....

EDIT: Ok now that I know how bad off he really is and how not okay he is...I am taking back all that selfish shit. I just want my baby to be okay
