Should I be worried or no?

I feel like I shouldn’t but I’m just asking for advice.

My husband told me I couldn’t go onto his phone to search google or anything because of Christmas presents I forgot about that and I was looking at his phone to search something since my phone had died and my husband has been searching this females name on google so I was like uh who is this and he grabbed his phone real quick and said a girl from his high school.

Okay? Why you searching her?

And why’d you act the way you did.

And he just apologized to me out of no where about it? Makes me feel weird..

I trust him but why he act so weird about it.
