Cheating suspicion from 8/9 years ago

[NM90]

Hello,
I’ve been with my boyfriend for about 12 years. I was 17 when we got together and he was 18. I’m now 29 and he’s 30.
When we were younger in our teens and early 20’s he went out clubbing a lot (that’s what the younger years are for right!)
His group of friends used to go out clubbing quite often with a group of girls when they were all between 19 and 21. I knew of these girls because one of them tagged him in a post once. I asked who they were and he said they were friends.
I had suspicions when I was about 20, about one girl in particular, I messaged her and she replied to say that I had nothing to worry about.
I’m now 29 and yesterday I had a suggested friend pop up on Facebook, it was my boyfriends friend. I clicked on his profile and because he hasn’t been on Facebook for years, all the posts from 2011/2012 were right there. I read a few comments that made me more suspicious about my boyfriend and this particular girl.
Me and my boyfriend are in a really good place at the moment, are planning to have our first baby soon and I have no reason to suspect that he’s been unfaithful in the last 7 or 8 years.
I have never been unfaithful, maybe some harmless flirting with a guy from work but I’ve never kissed anybody or taken it further.
Now I don’t know whether to speak to him about it or leave it in the past.
I don’t want to cause issues, do I speak to him and let him know what I’ve seen, or do I put it down to some harmless flirting from when he was young? We’ve basically grown up together from teens to adults.
Thank you!

I usually have zero tolerance for cheating and honesty, but in this circumstance, I honestly think you'd be better off not knowing. If you still had trust issues, or other relationship issues it would be a different answer. If it's eating you up inside you will have to bring it up, but if you wouldn't break up with him for it, wouldn't it be better to not know for sure? It was so long ago.

I don't think you should bring it up. It was a long time ago, he was young and really I think young people should experiment a bit. I find it faintly depressing tbh when couples have been together from their teens but obviously it can and does work, and is working for you.

If you trust him now and are truly happy, don't risk spoiling it. (My eldest is 20 btw - she is certainly not what I would call gown up!)

I'd leave this firmly in the past .... let it go and move on with your life

On a different note, OP. You mention being in a good place and planning for a baby. No mention of engagement or marriage.
If you are in the U.K. - I hope you realise that not being married leaves you vulnerable, once kids come along and you inevitably make some career sacrifices.

But back to the original question. You were barely adults. And it’s good he has a bit of a wild phase and went out a lot. Maybe this will prevent regrets/resentments/issues some coupes who met as teenagers seem to run into when they are in their 40s and feel like they missed out.

So - just leave last in the past and focus on your present. So much life to live for the two of you.
