I'm stumped.

Had a friend who is too touchy with me. The other day, we went to see Superman. She leans on my shoulder, links her arm with mine, bites my hand. I took it further and I pats her head, touch her face and she did not mind.

The problem is that she has a boyfriend. Is this behaviour normal? Or I'm just being breadcrumbed?

One time I asked her if her boyfriend is okay with her going out with guys. She said her boyfriend doesn't mind and that he too had other girl friends.
