So my bf and I have been together for almost 2 months. Everything has been going fine so far. He usually FaceTimes me during his break at work but whenever this female coworker is around him, he starts acting weird or nervous like he was caught doing something and he turns his camera to the side as if he doesn't want me to see what she looks like or if he doesn't want her to see or hear me on the phone with me. He has told me that she's a cool friend at the job but it still feels odd to me that he has to act so odd when she's around. Then when she walks away or stops talking to him, he'll start being overly affectionate and saying sweet things to me or bringing up old things we've talked about as if to try and get me to talk more about it. Like we've had discussions about certain things in the past that he would randomly bring up if she walks away and the stuff he'd bring up wouldn't even be anything related to what we would recently be talking about. It's possible I'm just overthinking it but I don't know how to feel about it.
