Thought I would come back an update, in case anyone was wondering how things are. I'll try and answer everyone's questions sorry if I've missed any.
Partner had not seemed very invested in this pregnancy when I first posted. Although this will hopefully be our first baby it is not our first pregnancy - we had a missed miscarriage and a couple of chemicals. I think he doesn't want to believe it in case we lose this one too. I was finding the contrast between how he treated me in our first pregnancy vs this one really hard as in the first pregnancy he made me feel really special and looked after whereas with this one he didn't seem to care that much. We have been together 3 years.
Previously he has been a bit selfish on occasion with using his phone with the sound on in bed but we had come to an arrangement where he has the phone on mute and I wear and eyemask so the light doesn't disturb me and that was working well. We don't have TV in the bedroom normally but did on this occasion as we were visiting family. I can't get on with earplugs - I find them really uncomfortable and on the rare occasions I do manage to get to sleep with them in I tend to remove them in my sleep.
My family are not nearby but I am not isolated from friends and could manage on my salary alone if I needed to (assuming it's not twins). Even if we did split it wouldn't be practical to move closer to family as there are few job opportunities there and housing is really expensive in that area. I'm the owner and sole mortgage payer of the property we live in. So I can ask him to leave if I want (although I really don't want to go through pregnancy/birth/parenting alone).
He came out of his sulk shortly after I posted on Saturday and we had quite a nice day. I went up for a nap Saturday early evening but couldn't sleep, did have a nice rest though (I have to be pretty much dead before I can successfully nap in the day). On Saturday night we negotiated a reasonable time to turn off the TV but then had another big argument after he said he "might" turn it on again on Sunday morning even if I was still asleep (he didn't in the end).
On the way home in the car on Sunday he made a comment about the state of the house being my fault (it is dirty, but we both work, I've been exhausted and he hasn't done a whole lot around the house either) and I saw red and shouted at him. I'm not normally an angry person and I think it might be the hormones but honestly I wanted to punch something. TBH the comment was not that bad and shouting was an overreaction but I think the accumulated rage from the weekend must have spilled out.
Weirdly the shouting incident seemed to trigger an improvement in his behaviour, I think the uncharacteristic rage may have convinced him that I am actually pregnant. He has done a few minor tasks around the house without being asked, watched the puppy for an hour last night while I had a lie down and has generally been much more supportive and attentive. He also bought me flowers. I also found him watching pregnancy videos on Youtube last night (on the sofa before bed not in bed!) and googling "5 weeks pregnant" so I think (hope) might be getting on board with this pregnancy.
