My wife spends more time with my kids than me and hence my kids are closer to her. They share everything with her but not me. This hurts me at times and I feel that they are drifting away from me. Please suggest me how do I avoid this.

I too experience the same thing as you. Its quite painful. My wife seems to be the one who apparently suffers and is in need of ‘more reassurance and emotional support’. I am actually the more affectionate person of the 2. Alienated my heart gently weeps as time progresses.
