Obviously, the passion in your marriage is over or at least fading away. You are overflowing with worry about what seems to be the decline of intimacy with your husband; you are afraid for the future and for losing your enthusiasm for life.
Your conclusion is so accurate that 10 years ago I would have changed my life, I never noticed what I was doing and because of my inexperience and I lost a great relationship without wanting it.
An adventure would only revive his spirit for a short time, after which he would feel frustrated again and seek more shallow sexual adventures.
I insist that everything changes with a little maturity, at my age I will talk to my partner and look for ways to revive the relationship, but we don't always have the tools we need to answer our questions, things happen for a reason, but if this post happened 10 years ago, possibly I was in a happy relationship, thanks for your wise advice, happy night.
