Thank you all so much for your help and advice, it's very comforting knowing you think I'm doing the right thing
I spoke to my boyfriend and told him I was staying and helping of my own free will and that he wasn't a burden, and his actions have in no way affected my decision.
He rang me last night quite upset, he said he does love me and he's sorry, he wasn't expecting me to handle the situation like I have and thought he'd just be a burden but he understands now that I do not see it like that.

Obviously I'm over the moon that he's realised I'm here to stay and support him, but I know he still needs a lot of tender love and care and this will be a slow process that requires a lot of time and patience- but it's a step in the direction
He's also agreed to do some sport with me next week which I read on these forums helps a bit so I hope he finds it useful.

Thanks again and any other advice you can give id appreciate massively xx
