Girlfriend swears that she didn't lie but something in me tells me there is more to it, how to proceed with this?

This is something I posted on some other forums but didn't get enough opinions.
I am in a relationship with my girlfriend for 6 years, live together for 2 years. She is sweet, caring and loving, has so many good traits and I would definitely want to marry her.
However, there is something that bothers me about one event. A few years ago she was at the bachelorette party and the next day she told me at first there was a stripper and after a few seconds she said that she is just joking that there was no stripper but that the maid of honor "acted" as a stripper for fun. I didn't think about it for years and then one day I was looking at some old photos with her and there was a selfie of MOH from that party with some guy. There was nothing on the photo except for his head, couldn't see anything else. The photo was posted in their facebook group for bachelorette party.
I asked a few more times because this was really weird, and she swears to life there was no stripper and she has no idea who is the guy on the photo. After all of this we struggled because of some other issues (she was somewhat secretive with her phone in general because she said she does not want me to try to read her messages from the time before our relationship). Her story about the party and all this is very convincing, she swears to hear life there was no stripper. I want to believe her, but something in me tells me something is off here. Why would MOH took a photo with some guy at bachelorette party and post it in FB group... my girlfriend said she has no idea who it is, that it might be someone's boyfriend. But then, why take a take a selfie with someone's boyfriend and post it in FB group...
I said that I want to believe her and that I would like to ask MOH who that guy is, but she is refusing to give me any contact to MOH or contact her by herself, because it is "stupid" that I don't believe her and that it will only embarrass both of us.
Did you guys ever had that feeling where the story is convincing but one thing feels off?
I really need advice how to proceed with this.

I'm not sure why you're arguing with people you disagree with.

Lots of people have said they'd feel similarly and advised to break up with her and yet you're crossing to argue woth people you disagree with.

@uijkor‘s misogyny shines through more and more with every post. I cannot understand why he is even on MN when he has such hatred for our opinions (unless, I assume, they slavishly agree with him).

As I said earlier, @uijkor - if you want an echo chamber where people only say things that will please you, rather than intelligent people who read your posts and form their own opinions, whether those will please you or not, then MN is not the place for you.

@SDTGisAnEvilWolefGenius - I think OP has posted here because he wants to spew anger and aggression at women as a kind of stand-in for his GF. Or perhaps that’s what it’s evolved into for him because we didn’t all agree with his approach. He’s even managed to post snide responses to people who have made supportive comments.

That said - since his GF is demanding to go through his phone on a regular basis, she’s also out of order and the whole thing sounds toxic.

Hopefully they’re both just rather young and will learn over time that this is not how a healthy relationship works.

When the trust is gone, then the relationship is all but over, isn't it? She's adamant she's telling the truth, but you don't believe her. If she changed her story and said she lied, then you wouldn't trust her because of that anyway. Whatever the truth is or isn't, you think she is a liar and you don't trust her any more. So that means you need to decide whether to end the relationship.

I really don't know what else you can get from this thread.

I agree completely, @Dery.
