<human>: We've only been dating 3 months
So my GF left her Facebook logged in and I just couldn't help but notice messages from guys, nothing too bad except for one from the night before. 

(the night before)
She was sleeping at my house and woke me up at 5 am saying she accidentally locked herself out when she went out to smoke because she couldn't sleep, so I unlocked it and she said "ill be there in a minute I was driving home because I didn't know what else to do" she finally came in DONE!, but I saw that she was messaging a guy about needing money for rent around 330am and he agreed to help and gave her directions to his place to get the money. She of course failed to mention this journey to me. 

Am I being a bad BoyFriend by looking at her Facebook? 

How do I bring it up without revealing my Facebook creeping?

Can you provide a brief overview of the text?
<bot>: Saw her FB, She met a guy for money and didn't tell me, How to ask her about it without being a suspicious Boyfriend?
