Maybe it's something he does?, I forgot where I went to, but I was at this state working and the men out there ( the ones I had to talk to, for business or just shopping ) will say " sweetie, honey, darling, or love".
So if your boyfriend does it a lot, he probably can't help it. The manager I had to she called me honey and her husband will say darling to me.
Sounds like he can't remember people's name, and who doesn't like a friendly flirty guy, that makes you feel special. Especially if he does it properly. I wouldn't let it bother you until he stops taking an interest in you, you know the signs he's met someone else.
