Omg. Why am I trying to be his friend instead of his WIFE?!???
A few reasons.
- because you see him hurting, and you want to comfort him;
- because YOU are hurting, and you want the comfort that comes with a more friendly relationship, and not the godawful adversarial one that accompanies adultery;
- because you miss his friendship, and always considered that an important part of your marital relationship with him? (I know I do -- my wife IS my best friend, by far)
It's all very understandable. But you can't -- at this critical stage -- turn to HIM to soothe you, and you damned sure shouldn't be soothing HIM.
