Search Results: calling someone names

So the day my boss was absent there was this guy who took the lead (I see this guy around pretty often but never had him as my boss) I honestly feel like he might secretly have something for me since I always catch him looking and like being around but I'm not so sure! But anyway on that day he asked us (me and my colleagues) to write down our names and tasks so he could get to know us better and we did, I was third on his list and there was someone else beneath my name... He started from the bottom of the list and started calling out #4 name and then moved to the very top of the list (skipping on me) and I was the last one for him to interview! Don't you find this weird? I mean he either would start from the top and continue or bottom, there's like nothing in between here or am I overthinking it?

I was in a relationship with a guy and we had a mutual friend, more his friend (even though he knew her through me but that's another story). She called him kitten also when I was around and I hated every second of it. Platonic he said but I didn't like it.

The word I think to me has a very sexual/lover connotation when you call someone else that. It's not a name for a platonic friend in my silly opinion. This became a whole thing as I had to bring it up multiple times but he said it was just a nickname and it wasn't a big deal, for me it was just too much and if she called him cat or whatever I wouldn't have cared. But kitten? Come oooon.

It's been months and I was wondering what people think of this. Am I being too insecure or is it just... not good?
Please share your opinions and vote if you got some time to spare? Thanks!
