Should I Be Worried About His Friend Girls?

He’s a helpful man, very caring and reliable. So I understand why his character attracts a lot of people. One example, I caught him with a girl at the gym, but he already mentioned he’s training someone so it wasn’t a surprise. He tells me she’s just a family friend and have been ever since high school and has a man. In his own words he told me, "No I do not like her and won’t ever try and get at her.” Another example, we were on the bed making out and suddenly his phone rang. He looks at me and said oops, then picks up. It was a girl, I can hear her a little bit, but it was muffling most of the conversation. She said what are you doing and he said I’m with someone. The call ended, he was like that was my friend and I said okay. After, we had sex and obviously it was on my mind still. Should I believe him, is he lying about these woman?
