I need advice...

My bf got a new position at work. He works around 10 girls. Since he started working there he gets ready and actually showers daily. He says he doesn't like talking to them bc he's there to "work". Today I heard some recordings of him talking to a girl from work about some music. In the recording he clearly is there with her showing her how to start a song on HIS phone. She seems very interested and he does at well too. It bothers me bc he says that he doesn't care about anyone that's there. But does this. There is no need for the girl to be that interested in a song. And why couldn't she use her phone and why does he have to be that friendly. Every time he comes home all he talks about is this girl he works with and how they are partners. He knows so much about her. I don't like it at all bc a while ago he became super friendly with some girl. The girl took it the wrong way. He later was talking to her everywhere (fb, phone, snapchat, ig, email, texting) and wouldn't even send me one text the whole day. I am across this is gonna happen with the new girl at work. I am 31 weeks pregnant and feel so emotional. I live w him and confronted him about the recording and how I don't like how friendly he is. All he said was that he wanted proof. The problem is that I found it In his email bc I was snooping. So I had nothing to show him. He said that he doesn't remember showing any girl his music. And that I am lying. But I heard it. Now he's mad at me. Idk what to do. I know he's not cheating but, I hate how he's so flirty and friendly w girls. Plus they all know I'm pregnant, so why would they talk to him?
