There is the possibility he might throw you out if you're not working and due to medical issues.
You should try to find a solution to avoid the situation from occurring. If he is adamant that he will throw you out, don't stick there. Things might get worse. It's better to contact your closest friend(s) or family members who will give you shelter and help you in healing and recovering from what you're ailing at.
If the man loves you, and understands the reason you're not working and because of your medical issues; there is no need in staying in the relationship unless you're married.
If you're married, you should seek legal counsel. If you aren't and have stayed for long in the relationship, you're entitled to share in the family's belongings.
Before you arrive at this critical decision, try talking with him about the issue. Involve others if he doesn't want to hear anything from you or to arrive at a desirable decision.
