New boyfriend keeps bringing up that I was on tinder when we first met

[Raddytin]

Met a man out at a gig around 5 months ago, at that time I was on dating apps, looking to meet someone. After around 2 months we decided to become official and I deleted all the apps then. In the time we were ‘dating’ I was on the dating apps but didn’t meet anyone (even for a month or 2 before that, I hadn’t had much luck on them. When we met he wasn’t on dating apps and said he had been taking a break from them after being on them for a while. Fair enough , we were in different places.
he keeps bringing up that he’s finding it hard “knowing I was on tinder when he was focussed on me only”. I’ve explained I wasn’t actively dating but we hadn’t chatted about being exclusive yet but I wasn’t actively looking anyone else and often this is how it goes at the start of a relationship before the chat about what’s going on.
he says he feels stupid as he didn’t know (until the exclusive chat) that I had even been on dating apps.
I don’t think I’ve done anything wrong? In fact even if I had still had a few dates I don’t think that’s wrong either but it just happened that I didn’t and I was quite interested in him.
I’ve told him I’m not going to let him make me feel bad for this when I haven’t done anything wrong and we could have easily met at a different time when he was also on dating apps.
am I being unreasonable? Apart from this it’s a lovely relationship but I don’t want to feel like I have to ‘defend myself’ or even explain myself when I don’t feel I’ve crossed a line

"But my rule is “if the relationship is less than 6 months old and you are posting on mumsnet about anything other than a barely disguised smug humblebrag about how marvellous your relationship is then you should probably end it.”

Yep 😁

Thirded. @Mumofteenandtween is correct.

It should be all shagging and staring dreamily at clouds at this stage.

I know you're the same age, but I do think that him being late 30s together with the fact you met irl and not on the apps, might mean that initially it might have been a case of different expectations for exclusivity. However:

he keeps bringing up that he’s finding it hard “knowing I was on tinder when he was focussed on me only”.

This is such insecure, controlling shit. He is never going to not bring this up, and will almost certainly add to his repertoire with comments about body counts, or clothing, or going out with friends and other misogynistic wank. This will only ever get worse. Time to get back on Tinder.

I’m married and I’m not sure if I still have a profile on a dating site. DH has never asked and I’ve not thought about it for about 8 years since I met him on there. If it turns out I hadn’t deleted the app/my profile he’d just think it was funny because he’s secure and not an arsehole and he’d a) know it was an innocent oversight b) not be looking for a stick to beat me with.
