Asking for married men only, what do you do next?

Married for over 10 years and have children, have a great sex life we have had many discussion about each others fantasies and enjoyed roleplaying and whenever another woman was involved she would change the topic but she recently openly accepted she likes women that way too and that she's been Bi-curious for a long time (not to my surprise tbh) but was afraid that i might like it too much(as any man would) and might lead to complications if we involve another girl/woman. I feel for her that she's been holding up for so many years and i am being supportive. Has any husbands faced this? Is it normal for a wife to hold up her feelings for so many years?
