Hard to say without more context but I have been in my current monogamous relationship for 10 years and others for multiple years before that.
It’s not supposed to be hard all the time. Sometimes your needs will get sidelined unfairly and things will seem rough. Sometimes it’ll seem like all you can do is bicker. However, if after multiple conversations and open dialogue about issues, noting changes then that is probably a sign of a larger issue of respect.
That sounds annoying and tedious!
