Thank you all for your replies. My son is a member on here and is fully aware of my questions. I just needed some unbiased opinions on what is happening, as I feel it's becoming a very unhealthy relationship. But he is smitten so finds it hard to be unbiased. He is reading all your replies and will ultimately make his own decision and, hopefully, seek help from you all if things go the way I expect. Again thank you all for your honesty.
