You can always do the initiating, but that doesn't mean shes going to want it too! What I would do... is totally set up a little romance in your house! Make it special and make her feel wanted. Make her feel beautiful and that you miss have that physical part of her. Let her know. Communication is key and also have an emtional side to everything.
DO NOT CHEAT!!! You've been with her for so long... is it worth it? HELL NO.
Good Luck!
