Overreacting is a sure way of getting your wife to run away from you.
Now :
Do you tell your wife that you love her on a regular basis?
Do you tell your wife that she's good-looking and sexy on a regular basis?
Do you bring her little "surprises" (flowers, perfume, etc) to surprise her?
Do you help out in the house with cleaning dishes, clothes etc?
I let my wife be when she answers a call or SMS, and doesn't want to tell me from who it is/was or what it was about. It's her decision. It might be something she's planning for me, or else it just doesn't concern me at all. I don't stress about that.
