Lex, it sounds like your boyfriend is going through some things too. Sleeping all day is not a good sign. Perhaps he's feeling your grief in his own way. Maybe he needs you to hug him?
I'm sorry you've been through so much. Losing so many people must be extremely painful. I don't know the situation between you and your Dad but I hope you both find the stregnth to work through it.
This may sound mean but remember your boyfriend probably needs you as much as you need him. Maybe he's feeling a little left out? I don't know. I can't speak for him but maybe he cannot voice his needs and ask anything from you in your time of so much pain and turbulence. Maybe just for an hour you can focus on whatever he's dealing with? Him sleeping all day is definetly not good.
I hope this doesn't hurt your feelings. I'm trying to see things from a different perspective. Your not feeling like he's there for you the way you need him to but he is there for you in his own way. You have to see he could be afraid of saying something wrong or hurting you which is why he stays vague?
I don't think you're as alone as you may think you are. Forgive him for not being what you need him to be. He's a vulnerable human being too.
