I'm sorry, but I'm having a very hard time understanding why you need your boyfriend's *permission* to get silkies ... with YOUR OWN money, no less!! I just can't wrap my brain around that. Plus, by your own words, he values some stranger's personal opinion about something more than your happiness. If you think this is love, we need to have a talk. I sure hope you aren't entertaining ideas about marrying him one day ... he sounds like he'd be an abuser.
Different strokes for different folks? I learned long time ago to leave others relationships alone. :/
