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.

hey hey, don't lose steam! Try not to focus on that fact. Start to pay more attention to your kids, what they like to do, the little things about them, and then create activities or moments around that. If you have to, speak with your wife and see if there's any way you can help around with the kids, even if it's doing the chores together. Cheers and hope everything works out.
