My Wife has A Lover And It Excites Me?

Your wife is a cheat and will continue to treat you this way. Put your foot down and commence divorce proceedings. When she has finished with this lover, she will find another. You will be in for a future of heart ache. The excitement you feel will be replaced by other less fanciful feelings. Let her go. Move on. Find someone who will love you and want you the way you need to be. Good luck.
