Touching at work

I was hired at the beginning of December and me and the manager grew quite close where he’d let me eat lunch in his office and give me extra breaks. We then started talking about more private matters like sex life and stuff... We spoke on snap chat a bit and the sexier I was , the nicer he treated me in work - I like the attention. He then mentioned that we should meet outside of work in a hotel but I told him I didn’t want to.

One day he lifted up my skirt and grabbed my ass. I laughed it off because I was embarrassed and knew it was inappropriate but was scared to stand up to him.

My question is, is it my fault I lead him on to do this with the pictures I sent and giggling? Because surely as my manager he should not be touching his staff, no matter the context of the situation...

thanks girls
