Husband still not back!

I dropped my husband at a house a few miles away at 8:30pm for a Christmas party. I’m 28 weeks pregnant and pretty tired, so I go home to bed fully aware that he’s getting a taxi home. I wake up at 4:30am and he’s not home. I text him and he says he’ll be home soon.... we’ll it’s been an hour and he’s still not home.

He went to this party only knowing one person and I wasn’t under the impression it was going to be a long night. We had made plans were to put our Christmas tree up today, but he’s not home😞.

We’ve been married for almost 8 years and he’s never stayed out like this, and not once has he gone out drinking heavily since I became pregnant. I have never had to worry about not trusting him, I just feel like this is out of character and I am getting paranoid 😞
