My wife hasn’t slept in the same bed with me for about 1-1/2 years.
Other than what your wife has told you, what else would you attribute to her not wanting to lay beside you?
What could you do to develop the attraction for her to want to hop in bed with you?
Steve with another man in the picture, either in person or someone she's been thinking about for quite some time, there really isn't much he can do to ramp up the attraction between him and his wife.
Well actually he could try one thing, emulate her behavior including finding another woman and ignore his wife and text, email, call this other woman on a regular basis and let his wife catch him doing this - this would change things quite a bit ;-)
