Questions: Flirting

Last night me and my girlfriend Jess went to a house warming party. Jess kept giving lots of her attention to another dude. She kept sitting him down and giving him massages with a massage tool. Jess seemed so intrigued with him it seemed like she was following and wanted to keep talking to him. Even when he was talking to others she kept watching him.

Later that night when he was leaving the party Jess jumped in front of him and yelled “you’re not going anywhere”, And was hugging pulling him back into a chair and gave him another massage. I felt uncomfortable but didn’t say anything because I didn’t wanna start a fight. I also feel like it’s double standard because a few months she got mad at me when I was talking to another woman for 30 minutes.

I know if I mention this to her she’ll break up with me. I’ve talked to her before about how I’m uncomfortable with her male friends and she threatened to break up.
