I need help 😩

So my co worker and I are really close but I'm so in love with my boyfriend.  I feel like I've caught feelings for my co worker but I feel like it's just a silly crush that'll go away soon.  The reason I think it is bc my SO and I never see each other because we're so busy and we live at about 30-45 minutes away from each other.  Idk what to do.  Go with the flow or say something about it 😞
