can my boyfriend be my caretaker or giver?

A friend can be a caretaker only.

It would not make sense for your boyfriend to enter a personal in-home care vocation just for your benefit. Many in-home care companies have a policy against staff members being assigned to family members or close personal friends (and in some states it is the law). So, the fact that he is your boyfriend would mean that he wouldn't be assigned as your caregiver anyway. It would be a stranger. Thus, your boyfriend should pursue whatever career path he chooses. He can help you during his free time if he is able to.

There are options for you out there, but it will cost money. Non-medical, hands-off assistance (cooking, cleaning) can average about $30 per hour, but will vary greatly depending on your location and the company you hire. Hands-on care (bathing, dressing) will be much higher. Google in-home caregiving companies in your area. A lot of them will say assistance for seniors, but the services they provide overlap with services for people with disabilities.

If all you need is occasional housekeeping, consider hiring a maid service. They usually run between $100 and $200 per visit. However, they won't assist with any personal or medical needs.

Update:

I read your comment in the other response. If your boyfriend is willing to give it a shot, I would suggest that he do the legwork of contacting the care companies in your area. Find out what kinds of jobs they have available, and what the qualifications are. He should also ask if there are any policies which would prevent him from being assigned as your caregiver, assuming he gets the job. However, you should understand that your care contract would be with your boyfriend's company, not your boyfriend. As such, you will be paying the company at their going rates.

Ask him. We cant tell you what your bf wants?! If he wants to be your slave thats up to him....not us.
