That question has no meaning here–too many variables are left out. Your best bet is to know WHERE you will live, what you want for coverage, then look at a site like this and see what YOUR actual choices are.

Oh, dear, love. You are in for a big surprise.

Your boyfriend needs to be employed by a large company to obtain the best health care coverage in America. If he does, ask about the company and/or insurance company’s policy on domestic partners. It is entirely up to the company and/or insurance policy whether or not you and your children qualify.

If you do not, you will need to get married soon in order to qualify to be on his plan, or purchase an individual policy for you and your children, which will run you approx. $300 USD or much more, depending on what coverage you select.

There is no nationalized health care in the U.S., so each and every time you visit the doctor - even with insurance - you will be paying something. Without insurance, a standard doctor’s visit with prescriptions will cost you hundreds of dollars.

Have a good long talk with your boyfriend about this, and I’m sure you will come up with the right solution. The sites below can help if you will need to apply for individual health insurance.

ahhh good old UK NHS
