Search Results: asking a guy to a dance

Andrea - He's friend of my best female friend. yesterday he took photos with me and sent to someone, I don't know why. Then he took me photos when I sat in front of me. Also he asked me "please walk around in the room I need to see your butt", I didn't but when I stood up and went in another room he said "Ohh look at this butt!", I didn't took it as an offence cause I often joke about his butt too. Later he told me "You are so cute and you look so gentle outside, little do they know how quirky you are".
Then I danced with Jace and even though that Andrea's female best friend danced too, Andrea took videos of me in his phone without me asking.

Jace

Jace has been waiting for me whole evening, but when I arrived at the party He was drunk and kinda touchy-feely to other girls. I was surrounded by other guys so that might be the reason he didn't approach me but when I was alone he would come and talk to me non creepily, saying me compliments. But It seemed like he spent good time even without me so I sticked another guy, Andrea and couple my guy friends. I noticed Jace would glance every now and then but that was all.
At last he asked the girl he flirted with to dance with him, they danced, then he danced with other girls and I was the only one he didn't ask to dance with, I was sitting with Andrea and drank a bit. Suddenly Jace came and asked "please dance with me ", I said nope Iam not a good dancer, " and he suddenly raised me up in his hands and took me to the scene, so I danced with him, It was not romantic because I spoiled the moment but we talked a bit. He didn't talk with others when they danced. Then we were so wasted that because of sudden move both of us fell down. He helped me stand up and grabbed my face for a second and then let me go.

Irwin
he sat by my side and pinched me all the time, then teased me when I talked with others. I didn't really pay attention to him but he said things and joked about me in a teasing way so I would hear.

Really get on with divorced coworker who is in his 40s.. I'm only 24 but I felt like we have a great connection. I've never liked an older guy so this is new for me.

He always pays me compliments like 'your amazing' 'I love you to death' etc. On works night out he was asking me about ex boyfriends, became quite jealous when other guys approached me and danced all night. Later that evening he asked if he could kiss me.. since then he asked for my number, we text a lot though I initiate most of the time, he spends a lot of time around me in work and he calls me regularly! No further moves made but he keeps asking me to go to next works do next week.. do I tell him I really like him or wait?

If if so.. how should I go about this? Can't stop thinking about him!
