Thank you, all. The good news is -- he cannot be swayed by these other women. He loves me and is devoted to me, this I know to be 100% true. He's not interested in anyone else.

s4ndm & seesaw, thank you for the validation. Erebos, he did turn and looked at me with a raised eyebrow when she had brushed through his hair with her fingers. He didn't know what to say in the moment, and neither did I. I don't think that by confronting her is being an insecure desperado or anything -- it is putting her in her place as needed, as others have noted. She needed to know it is unacceptable and that I didn't appreciate it, as her semi-friend.
