Sure, in the past I would have explained my reasons. In fact in the past I used to tell my family members everything about my life. But I learned that this often backfired for one of several reasons. My parents have/had bad tempers and arguments were common place. Confidences I had shared were often raised in an argument and used against me. Also, I have grown further and further apart from my family over the years. We are totally different people with different values etc. Whilst I respect their values, etc. They don't respect mine. Finally telling one family member is equivalent to telling them all. My mum tends to obsess over things wanting to know every detail. If I once mention a plan that I might have she will ask me about it repeatedly every time I speak with her. It's quite exhausting and also I find it invasive.
