Should I leave or Stick It Out ? ?

Wow! Leaving is hard especially when finances come to play and children (if you have any?) this is where you would want to stay and try to hang in there and get counseling (prefer coaching) to help make a situation better. Love and Lust are almost the same and Marriage is a tough job 24/7.If you can't set things straight with her in what you want then the answer would be leave. It doesn't get better take my word, what you see and experience is what you will have till you die. Unless she is devoted to change and make a couple for the benefit of you and her. Happiness is the key of life, why be drowned with sorrow and misery.
