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?

It is somewhat normal because mothers tend to oversee almost everything. It would be wise to have an open communication with her, find the right timing and think of ways you both can rekindle the partial lost of romance. Go on a date, have a trip it can help. :)
