Husband won't let me see his phone.

My husband and I have been together four plus years, married for 1. I've had insecurity and trust issues since near a year ago, I found out he was talking to his ex. That's over now and I forgave him.

Well today, he was showing me something on his phone, I forgot exactly what it was about, but he hit his tabs and I saw Firefox? I'm like who downloads Firefox on their phone lol only because literally everyone uses Google. I asked if I could see and he goes, "no"

But I don't see what the problem is?. It's not like I'm asking to go through your whole phone. He said about he dont remember what he doing on Firefox, like YouTube or something. but I couldn't see regardless.

I get out of bed because our baby just woke. And he mumbles, "it's ridiculous". I say, "yeah, it is".

I leave and close our door. He calls me fucking stupid ass bitch. I wanted to so go back in there, but all I could do is cry, so I didn't.

Really need thoughts or any advice. Thanks for reading
