My question involves a marriage in the state of: Virginia

My marriage of 2 1/2 years is ending due to my spouse's infidelity. I am active duty military and she is retired. She has a 80% disability and does not work, but gets her military pension as well as disability payments. We never established joint bank accounts, she has her own insurance, car titled in her name, etc. The house we live in is in my name only. I am set to retire next year after 30 years. My current active duty income as well as my future retirement is considerably larger than hers. With the marriage being so short, what can I expect to pay her in support, if ordered by the courts?
