Should I end my relationship?

I have been with my boyfriend for 2.5 years. In that time, he has been employed for 5 months before getting in a row with the manager and being fired. In the same time, I have more than tripled my salary, integrated with the local community and spent time volunteering to help charity. In contrast, he has got into arguments with shop owners advertising jobs, walked out on bar work, and refuses to do any kind of volunteer work.

He loves me completely, and I love him, he keeps the house perfectly clean, cooks for me, looks after me when I'm sick and tells me I'm beautiful.

But then I tell him there is a job going at the local leisure centre or wherever and he says "Oh, so-and-so worked there and apparently the managers are horrible" or "That's a rubbish job and only pays min wage". He is only applying for nice office jobs with good salaries that need experience. We have huge rows about this almost every single day.

We are about to sign a contract for a new house. If I leave him now, without payslips or a contract, he won't be accepted to get a flat and will be homeless. As I said, I love him, but he has been completely unemployed for 7 months now, and I just don't think I can do this any more. Any advice is much appreciated.
