My boyfriend has female coworker's numbers in his phone , Is this a red flag?

Anonymous
My boyfriend and I have been together for almost 6 years. We have always been upfront with each other on certain things we are not okay with. Recently my boyfriend transferred his job to a different location. He failed to tell me that has was working closely with 4 other girls at this place and had two of their numbers in his phone. When i confronted him about this (our contacts are synchronized through google) he said he didn't need to tell me that he had their numbers and that it wasn't my business. He also said that he had everyone's numbers at work in his phone but when I looked for other numbers they weren't there. I've had issues with him in the past getting too friendly with other girls and at the first sign of us having an issue he went to sleep with one of them saying before hand that we couldn't sleep with other people in the break... Sometimes when I go to pick him up from work I see him talking with them and when he tells me about his day fails to ever mention that he was with them all day. At this point my trust level with this man is very low and he just can't stop keeping things from me. I'm currently carrying his child and at this point I'm feeling very unsure of our future.
