is it possible to remove my wifes insurance benefits without divorcing her? (legal separation due to abandonment--by her)

My wife has abandoned me and has no contact with me, but she remains married because she has been diagnosed with cancer and needs my insurance. I refuse to divorce her for biblical reasons ( I desire reconciliation) but am perplexed with the hypocracy that she will receive benefits of the very marriage covenant that she refuses to acknowledge. I am tired of being dragged through this pain and suffering of separation (3 years) I have attemted suicide, and am very sick over the whole issue. I feel the need to press the issue to get a response from her. I take my marriage vows, which where made to her and to God, very seriously, and therefore refuse to dishonor her or God with divorce. I have been told that the only way to terminate her insurance, is to divorce her, or quit my job. Niether is an option to me. is it possible to file for a legal separation on the grounds of abandonement, and get some type of an injunction (or whatever it's called) to terminate her insurance benefits
