Should I talk to him about this before he leaves, or let it go?

I've been dating my boyfriend for 7 months, and we're both 23 years old. I trust him, and we're very open about our feelings in our relationship. That said, I've had some concerns. I know he hangs out with one of his ex-gfs, but he agreed to let me know whenever he hangs out with her. Likewise, he also makes the effort to tell me where here is and who he's with. He's also given me the privilege to go through his phone IF I ever feel I need to. When we hung out, I noticed he would flip his phone over and talked to him about this to which he said that when he's with me he doesn't want to acknowledge anything on his phone (unless totally necessary) and that's why he does that.

He's leaving for a one month trip tomorrow, and so he came to hang out with me for about 4 hours despite his busy schedule. During this time, we ended up using my laptop as he had to print something. To print that thing he needed to go on facebook and into his messages, at first he quickly went to his inbox and I wasn't really looking - as I understand the need for privacy. He then hand to go into his inbox again, but this time I WAS looking, and he made sure he retrieved what he needed to in a way that all his messages in his inbox weren't visible to me this time. I know this might be a minor issue, and I might be totally overthinking it, but it's bugging me. He's also leaving for his trip tomorrow so I don't think it's the right time to discuss all this - but it will ANNOY me for an entire month while he's gone. Should I let it go?

If there is something in the pit of your gut telling you something's wrong, you need to talk about it. He can't understand how you feel if you don't say anything. It's better to talk to him about it now, then for him to leave and allowing all this time and distance to cut between you guys and then when he comes back, you want to talk about something that happened along time ago. So, always, always communicate.
