My boyfriend doesn’t call me babe anymore?

I’m not trying to be dramatic but it just is starting to bother me. Me and him had a conversation last night if everything between us was good. And he said yes. I believe him but I just feel something is off. I don’t want to keep bringing it up...

The way he texts me is different. I don’t wanna become one of those girls who overthinks and ruins the relationship right before it even started.

He used to get excited and call me baby and text me nonstop.

He has a full time job and works hella. And I don’t wanna get mad over that. I just don’t know if I should end it (even when I care for him) or just push through it

Should I just stop overthinking??? I’m so confused
