Just separated from my husband, 18 yr old son lives mainly with him and 15 yr old daughter mainly with me. My ex is holding a huge party for her 16th involving all the kids chipping in money for booze, food etx (mainly booze I imagine). He isnt speaking to me so I can only find out what's planned from the kids. A load of the 18 year old's friends are going as well and they all drink and smoke loads of weed. I feel I have no say in this but I AM NOT HAPPY ABOUT MY SIXTEEN YEAR OLD DAUGHTER GOING TO THIS!! She is all excited about this amazing party which is incidentally totally unlike the things her friends did for their sixteenth ( meal out, small party for a few girls in the house etc). I have no control over this and I dont like the sound of it, it's not what I want for my daughter. Can I put a lid on this somehow without my daughter hating me??
