I (35F) have lived in my place for 3 years and recently my boyfriend (34M) moved in with me and on one of our first nights together he got very upset with me for not closing the blinds when I changed my clothes.

For context, I'm in the habit of changing my clothes in my room without adjusting the blinds. I live on the third floor and the closest neighbours are over 60 metres away, there are trees directly in front of my window that block any view and the blinds are always half way closed leaving about a 30cm gap at waist height. It's highly unlikely that anyone can see inside at all, and I have never felt uncomfortable or unsafe about it.

I explained this to my BF when he suggested I close the blinds and said that, ‘it’s something I’ve always done and I wasn’t really bothered by it’. His reaction to this really caught me off guard. He flew into a rage and said that ‘now I am his girlfriend the thought of anyone seeing me changing was not ok’ and that ‘I should close the blinds to make him comfortable even if it doesn’t bother me or anyone else’

For me this felt horrible and controlling. I haven’t been able to let it go since and the whole situation just makes me uncomfortable. AITA or is this a huge red flag?
