This should not be a problem--the law (and insurance policies) do not care about your domestic or living arrangements; all that is important for this purpose would be:1) Marital status--from what you write, you are still married, so that should not be a problem2) If your spouse has some other insurance planYou might have to update the insurer as to your address(es), if the policy requires that they be informed of any change in address; however, again, the mere fact of living separately should not affect coverage. It's a good idea, though, to double check the policy to see what requirements, if any, you have to meet in this instance. Good luck.
