Hi debs - have the school got in contact with you about her not being there? How did she meet this boy if he lives 100 miles away? It sounds like you are in contact with the boy's father, which is a good start. If you can keep that line of communication open, at least you will know whats going on. What you don't want to happen, is the boy's father throwing them both out. At the moment at least she is safe.
The trouble with teenagers Debs, is the more you tell them what you want, the more they rebel - I have one just the same.
I think for the moment, just communicate with the boy's Dad, let him keep you up to speed on what is happening.
When she has cooled down, then try to speak to her again. Perhaps suggest both her and the boyfriend could come and visit you - no pressure - just a visit .
I know its hard debs, but try and keep your cool - the more you question her and bring up her future career, the more she will back away.
When my son gives me grief - I totally ignore him - it works every time.
Lets us know what happens debs - I am sure this will all blow over.
As for your ex - when he rings, just put the phone down on him, don't waste your time and energy.
You sound a lovely Mum and I am sure your daughter knows this, but at the moment she is in love and all reason goes out of the window.
love Denise xx
