My LTR updated her profile picture today(she was already having it on FB but not as profile picture).

The photo's quite a good one, wearing a sexy dress where she's holding roses. I didn't ask anything about it as it was an old one.

As we were talking about shit, she told me that she had an argue with her girl friend because this girl ironically commented on the pic:'nice flowers, I'm wondering who gave them to you'. My LTR got angry and confronted her about it, deleted the picture as well.

So without me asking she confessed that the roses were from the guy who wanted a relationship with her right before me. She told me in the past about him, they didn't have a proper relationship nor sex, she was flaking on him and ghosted the guy when I've appeared.

I know that's just a photo from her birthday and I'm not bothered about that guy. Even if he looks beta, there it still was something beetween them. If that shouldn't mean anything, then why she deleted the picture when she had that argument with her bff?

Isn't it common sense that you shouldn't have a fucking picture of you looking at the flowers given by the guy who you almost had a relationship with before you met you current LTR?

She feels that she's done the wrong thing now and asked me right after:are you gonna be upset on me?

Guys, how should I proceed? Am I being right or wrong?
