I don't really know if Aibu or not, things between me and dp have been odd recently and just not feeling as close as we used to.
We were watching a series on TV at about 10pm and a friend rang me out of the blue, I answered and she didn't seem herself and wanted to talk and asked if I was free to come out with her, I said would tomorrow be alright instead as it's late and I'm in pjs.
It was a very brief call and I was on the phone for a couple of minutes and went to speak to DP as I was a bit concerned, DP was sat in the conservatory and just said 'well just tell her to come round or you'll just keep going on about it'. I said 'well I wasn't going to keep going on about it all night I just wondered what you thought'. We've had a really busy few months so it's not like I go on about friends all of the time 
DP said he was going to the bathroom so I was sat thinking and text a different friend who is also friends with let's say friend A. Friend B rang me back immediately and said she hadn't heard from friend A in a while and had been worried about her recently. I said 'I'm going to arrange to go out tomorrow if you want to come'. As I was talking DP walked in saying something and presumed I was talking to friend A, I said 'don't worry come in it's only friend b' and as I was saying it DP didn't even listen and slammed the door as I was talking to him.
I ended the call a minute later and presumed we would just carry on watching the series as we usually stay up late watching it at the weekend, as I opened the door all the lights, TV and everything had been switched off. I went upstairs and DP was in bed.
Now from the first call from friend A and me putting the phone down to friend B this had been just over 5 minutes and DP had been in the bathroom for most of that! My friends never ring so late and I don't talk on the phone or answer in the middle of something usually but as friend called so late I was concerned so answered the phone. DP will often answer a call while we're having a conversation or watching something and be on the phone a lot longer so I didn't see that this would be a problem?
I asked DP why he was in bed and he replied as follows
Me: DP why have you come up to bed
DP: because I'm tired
Me: oh I thought you wanted to watch that series for a bit longer
DP: well I'm not going to sit like a dickhead all night waiting for you to finish talking
Me: (a bit shocked) why would you be waiting like a dickhead I was on the phone for 5 minutes and you were upstairs
DP: well I'm not going to sit waiting for you all night go and watch TV if that's what you want to do.
Me: okay well i don't think you need to say you're sat waiting like a dickhead when I was just seeing if friend a was alright.
DP: I'm not going to argue it's just a phrase isn't it
Me: okay, well i'll probably just come to bed, do you want a cuddle
DP: no
And then acted normal the next day. I know this doesn't sound like a big deal but there's been few things like DP has made a lot of comments about me wearing makeup and getting 'dressed up' for work and says it's just 'a joke'. But says it all of the time so it kind of doesn't seem like a joke..? AIBU??
Thanks if you've stuck with this long post!
