How does a woman show possessiveness in her body language when she is with a man?

Just curious, I was with a couple and my boyfriend and this woman constantly put her hand on his chest when standing next to him and taking a picture and he just stood there without moving in closet for the picture. It just looked a little strange? Any thoughts?

She’s showing interest. And, woukd likely be a good time if she’s got balls to touch him in front of you…

I was just wondering... I have a boyfriend and wasn't asking for me. She looked insecure that's why:

Did that girl touch your boyfriend❓ That’s what I got from description?

Usually by showing affection, touching and kissing etc. Putting her arm around him. Also giving you glances that aren't exactly friendly.
