Am I Being Played

My wife & I had a great sex life, but been a year that she has talked about having that exciting, take it to the edge kinda sex life again, but we haven’t done anything at all, she complains about talking about sex, it should just happen & this is a woman who did nothing but talk about it, want it, talked about her fantasies & now nothing, went from 1 that you only read about to nothing at all, even says it’s to embarrassing to put on a show with her toys that she had to have, all she talked about until I finally showed interest again, now she’s always coming up with an excuse, doesn’t go anywhere with me just stays on her phone, Tic Toc, snap chat, and so on , says she doesn’t have hidden accounts but I know she’s lying, been married 29 years, says that the stuff she told me about when we 1st met, like being with a girl, just every guys dream girl, now she was just lying, telling me what I wanted to hear, doesn’t remember most things, I call BS but ok and now just feels like a game , need advice, what do you think, Thanks
