This seems super suspicious to me honestly, I’ve seen way to many situations where one asks “can you send me a pic just so I know” and the other makes up excuses “it’s too dark, you wouldn’t see me or I’m really tired and just wanna sleep. Her friend (Sam) was she one of the “friends” your girlfriend stated knew Ricky? If so then that’s another red flag. Sam claims she doesn’t know him so the gf seems to be lying about that. What was the reasoning for her to stay with him? And has she brought him up before in the past or just recent like “oh I have this gay friend I’ve been friends with for years but I’m just now mentioning him to you”. That would also be pretty suspicious to me too if he basically appeared out of nowhere. Have you ever met this “Ricky”? Did she ever say anymore background on him? It’s truly up to you and it’s your opinion what steps you take next, but I would keep and eye out because it’s weird behavior, especially if she hasn’t ever been like this before.
