Should I feel bad

So I’m just going to put this out there.

7 weeks ago we had our baby. we have been doing really well overall. No fights. I say that because everyone told us with a new baby you’ll fight and say things you regret out of being tired.

Anyways I was snooping since I’m home all day atm and saw on his email he emailed a jewelry maker and CCd his mom pics of my dream ring. This was early September btw. So I saw the jewelry maker emailed him back asking for more details but he never emailed back. It’s been a month.

So then this last weekend we got to skip away for us time without the baby. We both drank some and at one point idk how it came up he mentioned the future being uncertain. I felt like that was maybe aimed at me.

Backstory - he oriogionally didn’t wJg to be a dad. He is so happy he is a dad now and I chose to keep her.

Well anyways he and I were texting today and I asked if he’d ever consider more kids. And he said “Yeah. But if you asked me 5 years ago if I wanted a kid I'd say no. So theres no telling what I'll want in 5 years”

So I guess where I’m going with this post is-

Do I have a right to feel worried about our future? I feel idk like he’s uncertain. Also he knows my phone password and I don’t know his and he’s asked me lately who I’m texting which he never does. I’m an open book. Should I be concerned HES doing something he shouldn’t be and that’s why he’s acting weird? Btw I got to his email on our joint computer.
