Struggling to get over a date

[LR188890]

So, I've been with my OH for 3 years. Back in 2023 we had an argument and split for approx 2 weeks. Last year I found out in those 2 weeks we were apart he was on a dating site and went on a date with someone.
It was just one date but quite a lot of messages between them. The woman he went on this date with found me on social media last year (a year after the date) and sent me ALL of the messages between them, a pic of the flowers he sent her just after the date (it was her birthday). She said they were arranging another date then he just vanished, ghosted her and blocked her on everything.
I did confront him, he said he felt worthless after our argument and put himself on the dating site to feel better and blocked her when we got back together. I agreed to try and put it behind us and move forward but 10 month on from me finding out about her I'm still struggling. It hurt reading the messages he sent her. He told her he felt a connection with her, that he couldn't stop thinking about her. He said he didn't mean any of that and was just saying it.
She told me he lovebombed her and it affected her mental health when he ghosted her. Sex wasn't involved, she said it was a bit handholding and a peck on the check.
I can't stop obsessing about it!

Let it go.This woman sounds unhinged,hope you don’t own a bunny

Tbh the only thing he’s done really wrong was ghosting her. I expect the things he said to her were to try to convince himself that things would be ok and I doubt they were said to hurt her deliberately. The flowers for a birthday were quite thoughtful.
He ended it as soon as you got together. He should have been nicer about how he did that but that seems to be an expected way of the dating world now unfortunately.
He was obviously pretty upset about splitting with you and you do stupid things to make yourself better.

She just sounds unhinged.

Move on and forgive if everything else is ok.

Nobody's making anything up I commented my opinion. This is an open forum and people are allowed an opinion that differs to your own. I'd say someone who's kept messages from a bloke for a whole year is unhinged and has a weird obsession. Her other half has admitted he entertained dating the woman it's not impossible that he gave her false hope and promises before getting back with his Mrs.
