We're cuddling and watching a Halloween movie after dinner. Throughout much of the movie she sends texts to a married male work friend about the movie. They both love this movie and share humor about it at work. Okay, understandable. But the texting increases as the movie progresses. I'm getting annoyed. She begins to explain to me her relationship with the friend, telling me they share lines of this movie at work quite often, and she tells me he's married. Okay, she probably is able to tell I'm annoyed and feels the need to explain herself. She goes on to tell me that they once ate edibles together. She tells me that during her out of town conference they might sit in his hotel together, eat edibles and watch this movie. Even though I feel disdain towards her in this moment I can't help but laugh internally at the reaction she's attempting to get out of me.

I try to play cool and not react. I noticed that she sometimes plays these games where she tries to gauge my reaction to see if I'll attempt to control her or to see if I get pissed off. She rarely ever follows through with the things she says about hanging out with male friends. I don't know why she does it. Her last LTR was very controlling, so she always tries to gauge whether I'll try to control her so that she can tell me off.

Why do you think she does this kind of stuff? How should I react? Is playing cool and pretending like it doesn't bother me the right move? Sometimes I wonder if she does this kind of stuff to gauge whether I'm okay with a polygamous relationship, which I'm not.
