First time posting as I have no one to talk to about this.
DH and I have been together 12 years, married, 2DCs.
We were having a lovely lunch and a few drinks a few weeks ago. My DHs birthday is coming soon and I was asking if he could do anything for his birthday what he would do? He has been very busy at work recently and jokingly said "I would retire. No more Barcleys (company's name changed), no more blondie..."
I questioned it but he suddenly changed the conversation. Our children were around so I left it.
We discussed it later that day and he said that it's just a random comment and that he was drunk. I asked if there is OW at work but he said there is no one blonde at work.
I know I shouldn't have done it but checked his messages. I found some friendly (mostly work related) messages with one of his colleagues. She is blonde and very attractive. There is nothing to suggest cheating/affair. Although the messages are quite informal, emoji's etc.
He has never given me any reasons to think that he might be cheating. He is not secretive with his phone.
I am generally anxious and tend to overthink things. Am I paranoid? Am I overthinking this? I am really struggling and can't forget what he said.
