I have been happily married for two years - have a solid relationship with dh, good sex etc. However, someone new has started at my work and I find myself quite looking forward to seeing him around and sort of admiring him from afar. When I have spoken to him a act a little gigglish and girlish in spite of myself and looking back must have looked a prize fool. I would never act on this, but is it harmful to feel this way?
