I have a DP of three years, whom I love very much. He lives mostly with me and my DS and has given notice on his rental property that he'll be moving out from in March (his landlord hasn't found tenants- friends with them so know this- which leaves it open to changing if things went that way). DP and I had a lovely Christmas, however we met up with his (adult) children, which in general was lovely, however I had a conversation with one of his DC which made me uncomfortable. I brought it up tonight and he's really annoyed at me, saying I should've kept it private/in confidence. Maybe I shouldn't have said anything, but it was concerning him and it was different to what he'd told me, hence I brought it up. The whole conversation was less than a minute long and now he's really annoyed at me, as I said for 'breaking their trust' by telling him. I don't tell him most conversations I have with his DC, however I did this specific one as it directly contradicted something he told me. He's really annoyed that I'd tell him anything they told me in a private conversation. I have anxiety, so I catastrophise everything in my mind, but I'm worried he's going to break up with me over this. We're meant to have a weekend away tomorrow and I'm now worried he'll be so annoyed, that it won't go ahead. I've apologised to no avail. He's really annoyed/upset. AIBU in thinking that he might be considering breaking up? He seems so annoyed, I'm panicking so much as I understand that it was a private conversation and maybe I have fucked up massively? The reason I brought it up at all was that I didn't even understand why they brought it up, it seemed very random.
