To wonder why he’s lying?

[Berrydool86]

I have been with my partner for almost a year now and we have been through our dating history and cleared up the past etc. When we first met my friend and I googled him, you know just to make sure he wasn’t a serial killer! Well we found a news page about a fire at his house (I knew about this) and it showed a photo of him and woman labelled as his fiancé. I had no knowledge he’d ever been engaged to a previous partner. I outright spoke about marriage (when my cousin got engaged) and asked him if he ever had been or wanted to be. He said no he hasn’t but he’d like to. He has never introduced a woman to his parents but me, so if he has been engaged why hadn’t they met her first? I know news papers can get it wrong and it could have been a mistake to label the woman as his fiancé, but if she was why isn’t he being honest? So it’s 10 months on and I’m still confused why he’d hide that and I don’t want to admit I saw the news site to confront him as it feels like I was snooping!

You need to ask him about it- frankly it's weird you haven't already. You believe he is lying the paper is correct and you have given him no right to reply?
You could just say you googled yourself and him- you don't need to say you have had this info for months

That's weird.
Maybe it was just a silly little thing. My boyfriend 'proposed' to me when very young and I went around saying I was his fiancé but there was nothing to it.. absolutely no intention of getting married at the time. Just a silly little pretending to be adults thing. We were teens.

Were they very young when this picture was taken?

I am not sure why you think that talking about past relationships is ‘clearing up the past’. Or why you think when they meet and start dating a total stranger - that people have to open up completely, especially about past that may have been painful.
Whatever went on in his past relationship with her is not your business. If and when he is ready to tell - he will tell you.
At 10mo in you have no right to ‘confront’ him about something like that.
