Is it weird?

So I work in an office, I had some drama with a few females going and currently don't talk to them. They started some shit up about me. I am close with this one guy who works there, I spend all my breaks with him (he's old enough to be my dad lol) but he has been the sweetest person to me since I started and always has my back and we got closer. He's currently on vacation, which has left me alone all this week so far. I told my husband how it sucks working without him there. He's on a 3 week vacation and I said how it was going to be a long and tough 3 weeks. My husband knows everything that goes on, I tell him everything. He told me that it's weird I'm "missing this random dude that he doesn't personally know". But my husband has friends at his work and has mentioned how his shift sucks when they're not there. I don't really see what the difference is but my husband is accusing me of liking this guy over this. I feel like he's overreacting and it's normal to miss a coworker ? I've worked out a few different places and always miss it when the people I enjoy working with aren't there.
