Search Results: why was she twitching

So, I literally hadn't seen my boyfriend properly for weeks there because I've been busy with university and exams etc.

Anyway, during the time I've been studying. He had a work night out last week, and had texted me saying he was almost home at around 20 past 11 at night.

Yesterday I saw him properly for the first time and had said that he had ended up not going home and went to a local night club with some of his work mates. He told me he ran into the secretary from his work (Emma) at the nightclub and asked if he could stand with Emma because the club was full of 16/17 year olds. Emma and my boyfriend are both in their 20s.

He then told me he'd apologised to her at work when he saw her the next day, and I asked what he'd felt he needed to apologise for. He said it was because he'd been dancing and swinging Emma and her friends around on the dancefloor while he was drunk and was nervous in case he'd embarrassed her and her friends. I immediately thought to myself... why care whether you'd embarrassed her or not?

He then went onto say that he thinks one his workmates had mentioned he 'used to have a thing for Emma' at some point during the night (why I needed to know that, I don't know) and to that I said "are you sure it isn't you that has a thing for her?" to which he replied "you better be kidding! No, I don't fancy Emma" but as he said that, his eyebrows twitched nervously. And it made me wonder if he's lying to me.

He also mentioned someone at his work said they'd saw the videos of him from the night before and he said he felt nervous about that. Why feel nervous about someone taking a video of you as well?

I just don't know what to think to be honest, he may well be telling the truth and I'm making a big deal out of nothing, but it made me feel kinda suspicious.

Thoughts?

Skipping the details: First thing he mentioned to me was that he liked the way I walk which I don't know if thats because he is thinking sexually? Why would he be watching how I walk? Also I caught him looking at my behind a couple times -_-
But then recently he started to say stuff like about how I make a certain facial expression when someone says something dumb/annoying. Or how I bite the corner of my lip when I'm writing something/thinking very hard. Or how my eyebrows move around a lot when I'm holding back from saying what I really feel (because it would be rude). Or the small twitch/habit I have of scrunching up my nose when I'm stressed. And other things I didn't even notice that I do until he mentioned them. He just mentions them in passing like its nothing even though no-one has ever noticed these things even those I have known for years. Then he'll go right back to making sexual jokes like a fuckboy.
Is he just a douche? The small sparks of genuine interest have me confused. I can't help but think he's just working extra hard to get into my pants. Or is he covering up the fact he might like me with douchiness?
