<human>: A little background... we just moved into our apartment together maybe a week ago. We've known each other since 6th grade, and he knows all about my past relationships and the events that took place to end them. My last relationship ended when my ex left his Skype open, complete with full conversations between him & a girl he was playing video games with dating back 6 months from when I found everything.

Situation at hand: Last night my current boyfriend got home late from work, I woke up for a little while to hang out with him and chat. He was using my laptop to Skype with a friend, and I eventually got tired around 3:45 am and decided to head to bed. He told me he'd be crawling into bed in about a half hour, and kissed me goodnight. 

This morning, I woke up and read my book for awhile. I decided to browse the internet, so I went to the living room to grab my laptop. Upon logging into my computer, I find that skype is still open, but not on the conversation with his friend. Instead, there are 4 or so outgoing calls placed to random women.... none of them had answered. Another interesting detail, all of the women are black women, with semi-provocative profile pictures. All calls were placed around 4:50 a.m. 

Needless to say, it instantly brought my past situation to mind, and really ripped the scab off an old wound. Boyfriend is still asleep, I drove to my parents' house to take a breather because I don't want to point fingers or get angry with him without knowing what is really going on.

I don't know if he was just goofing around on Skype, or if this is something I should be concerned about. I don't even know how to approach the situation. We've never had any trust issues before, and we're always open with each other. He didn't seem to try and hide the fact that he was doing this; Unless he just forgot to log out of Skype. 

I really would like some sort of an opinion before I go home and try to approach the situation.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My boyfriend is making Skype calls to random provocative-looking black women at 5 a.m. How do I approach this?!
