When I was a manager I had a style of leadership when it came to encouraging and directing those with reluctance; whether it be to help themselves or perform at work. I have realised that my boyfriend does the same when it comes to encouraging me.

I would give the individual options. When it came to tasks they would be given a choice of do A or B. Doing neither wasn't an option.

My boyfriend once did the same with me. "Let's do ________ or we can do __________." Not doing either is simply not a choice. It doesn't have to be asked in a way that is an ultimatum. It can be done in a manner that appears encouraging. "Hey wouldn't it be great to get out..... A or B sounds good."

Obviously there is no guarantee this type of prodding won't backfire. As others have mentioned there comes a time when you simply can't put yourself out any longer - especially when your own mental health is being jeopardized. it may come down to asking yourself if standing by this individual is a disadvantage to you. Protecting your own peace of mind in no way is an admission of failure or being unkind.
