I'm very confused?

I have recently gotten closer with a work friend, we have been going out more often drinking and going on long drives. I have a boyfriend and he has a girlfriend. But today he has gotten very touchy with me. He held my hand quite a lot and hugged me twice (he has never hugged me before) he then kissed me on the hand which is the weirdest part to me. He touched my hair a lot and cupped my face. I'm so confused please help.

Update. I want to address what it is I'm confused about and it's about the guy and his intentions with me. I see him as just a friend as I love my current boyfriend and I don't hide any of this from him I told him and he is a little worried about what the other guy is doing. But he trusts me fully, I need Advice on how to address this with the other guy as I don't understand what he is doing?
