Crush but married

So I’m happily married but my husband isn’t 100% ready to have kids. He told me he wants them, just not right now.

An attractive young male at my work that I’m friends with told me that he wants a family sooner rather than later and all of a sudden I have a crush on him.

Is this normal?? I’m freaked out. I’m hoping it’s just my hormones. As soon as I get home from work I’m happily with my husband and think nothing of it. But when I go to bed, it pops back into my mind. I think I’m attracted to him but also his want for a family since I want it so bad?? Ugh. I’d never cheat on my husband. But this is new and freaking me out. Looking for advice. 💕
