You can still file for divorce, regardless of whether she will continue to be eligible for any of your benefits. Divorce can raise some complicated issues, and you don't indicate how long you've been married, whether you have any minor children together, own real estate together, or what benefits she is specifically concerned about losing. Consult with an attorney to discuss the specifics of your situation, and your options.
