So, my BF is an only child. He is very generous, charming with other people, talks a LOT when we're out (in company or just the two of us) but withdraws the moment we're alone, preferring his iPad to my company! Is this a typical only child needing space, or should I take the hint? He says he loves me and that I'm his best friend etc etc but this is the first experience I've ever had of being 'cut out' and it makes me feel quite lonely.
