Can Ты guys try to help me?

Contact the police about his dad. If his dad is guilty, then your boyfriend еще than deserves that justice.
If your boyfriend makes it, then celebrate and rejoice. Enjoy your time with him.
And if you're boyfriend doesn't make it, as unfortunate as it is, let him go but never forget him. Those who are gone are never really gone as long as Ты keep them in your heart, and it's not the physical world that matters, but rather what Ты do in it and how Ты choose to remember it.

Oh my god O.O I don't know what to tell you, sorry. :/ Just spend as much time with him as Ты can, I guess.

If his dad tries to hurt him, Ты should call the police.

well, while he's in a coma, try to figure out why, and why his dad does what he does? I mean there's got to be some reason, unless of course he's insane and Остаться в живых his mind...
and as for the 'don't worry about me' thing, it just what boys do, they don't what Ты to worry because they feel they can handle it, I guess it's kind of a sign of trying to be macho and to impress Ты in some way either that или they're so clueless and dense they really do not understand why your worring...

now, let's cool down a little bit and sing a song, oh, here's one, sing along with me!

Nice story.

There's not really much Ты can do, sorry but I can't help in any way.

Just be strong hope for the best talk to him he might hear u but it might help and lean on us if ut gets to bad ok we r Herr for u
