20 yrs with same woman and 3 months ago she sits on bed while i'm watching tv hits mute and says' "i'm not happy i want a divorce". I was completely shocked and taken aback. Not two days before this she is looking in my eyes and telling me i'm her soul mate and she can't live without me. I was devastated but believe i've gone through the stages and now i accept it. But i occasionally get very lonely. Is this normal?
