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?

Speak to her about it. Given our education system, it is natural for her to be worried and become very involved in your children's education. How about planning a family vacation? I'm sure your children could use a break too! Also, help her out around the house and with the children so that she will be less tired. This way, both of you will have some energy to help bring back the spark in your relationship. Cheer up! Get someone to help look after the children and go on a date! ;)
