My husband I have a close girl friend who we became close with about a year ago. We have a joke and call ourselves 3 sum because that’s what everyone around us at work , thinks we are. Long story short, last night while at work she put her leg over his thigh and it bothered me a whole lot. He didn’t do anything about it and when I brought it up to him he ONLY found it inappropriate because we were at work, he claims his sister and cousins do it all the time and it’s not a big deal. I found it inappropriate because I feel it’s an intimate thing that couples or people who like each other do.

Can someone please help me out here and let me know if I’m being dramatic and jealous or if I’m in the right
