Hi @rph91, I moved your message to the Women's Health group. Bacterial vaginosis (BV) is the most common vaginal infection. It is a type of vaginal inflammation caused by the overgrowth of bacteria naturally found in the vagina, which upsets the natural balance. Why these changes occur and whether the disorder is sexually transmitted are unknown.

Women in their reproductive years are most likely to get bacterial vaginosis, but it can affect women of any age. The cause isn't completely understood, but certain activities, such as unprotected sex or frequent douching, increase your risk. Sometimes earlier infections can return. I wouldn't be so quick to assume that she is cheating. The infection is not proof of infidelity.

It sounds, however, like it is time to talk openly about your relationship. You said you're going through a rough patch. Are you able to talk about the relationship without talking about cheating? Maybe start with how you're feeling.
