We have been married for 14 years and have two kids, but my wife is increasingly getting involved in my kids life and studies. So much that she has started ignoring me. I feel very lonely. How do I get her attention back?

You could also try to get involved, that way she'd spend less time. You pick the subjects you're good at and help with those. It can get really overwhelming for mothers if we have to do everything. Having a spouse get involved even improves bonding.
