Should I be concerned if my boyfriend talks to my best friend more than he talks to me?

So my boyfriend of two years was never really a social person. One night before I left for vacation with some of his family, not him. On a girls weekend. I got him to come hang out with me and my best friend and they were joking around and started texting each other. I found nothing wrong with it. They hung out while I was out of town and now they text all day long and both get mad if I try to touch their phones. Should I be concerned or should I trust them?

I know my boyfriend has never thought about cheating on me because of some of the conversations that I did get to read but I know my friend has had sex with an ex of mine before. I wasn't that serious with that boyfriend but this one I'm really serious with. I need opinions because my other friends are really making me think negative
