After 12 years of raising my stepson now 16 with his dad he left a note on the door and his mum took him to live with her (no warning or discussion)He is not going to school (year 11) and has only been in touch once after I sent him a card and easter egg. He's been gone two months and not responded to last note inviting him to visit over two weeks ago. Mum neglected him when very young and worried about what kind of life he's now leading. Dad is very very hurt. What would you do? I don't what I feel about him anymore but I used to really love him.
