AIO, Boyfriend suddenly gets privacy screen

I'm already aware that I have an anxious attachment style with a fluctuation of avoidance in and out, so I don't know if it's me but I can't shake this feeling of fear bordering on paranoia.

My boyfriend, has had hygiene issues that have bothered me as well as generally not seeming to care about his appearance. I never minded outside of the hygiene but now, he's dressing nicer and bought a privacy screen for his phone, showers regularly and is wearing cologne when he goes to work. He told me the privacy screen was because of porn but we've been together 2 years now and it just seems weird to me accompanied with everything else. He said him taking better care of himself is just because he's happier

We had a talk and he said all the right things. It settled me down a little bit but I still felt a lingering fear in the background, then today he told me he bought product for his hair and it sent me into a spiral again because.... it just seems very sudden for him to be this invested in his appearance. If the privacy screen didn't happen at the same time, Idk if I would be freaking out like this.
