Nerves... anxiety?

I'm pretty certain this is normal, but I'm hoping to hear similar stories. We are 4 weeks (27 days) to due date.

On one hand, we are THRILLED that we are so close to meeting our little baby girl.

On the other hand, I have thoughts like "omg, did we do the right thing? our lives as hubby-and-me will never ever be the same. what if he doesn't love me like he did before? what if our sex life becomes nonexistent after baby comes? what if our relationship just falls apart? they say parenting tests your relationship... what if ours doesn't make it?"

I keep these thoughts to myself bc I don't want to give my hubby anxiety. He's never given me any reason to think that anything would change. He talks to baby girl every day... kisses and rubs my belly... warms my heating pad nightly for my pelvic pain... makes sure I'm eating and gaining weight... etc.

Someone talk some sense into me.
