Met someone on OLD about a month ago. Chat was surprisingly efforttless and fun. Soon arranged a date. That went well too, and by the end we fancied each other rotten. Second date arranged. Also fun - we kissed and, unplanned, ended up DTD. Third date. Still good, yadda yadda. Agreed to go exclusive so we can focus on each other and give it a chance to develop. We're, slowly, opening up about having feelings for each other.
Fourth date in a couple of days. I'm now noticing I can't concentrate at work and feel nauseous quite often. Is this me falling for this person or just a bug? I divorced five years ago and have dated a bit, but no-one went beyond the first date before this person. I was in a decade-long marriage before that. So the last time I "fell" for someone I was in my twenties (and I'd known them a while beforehand as opposed to it being a complete stranger). I'm in my forties now, and a bit less starry-eyed following the divorce.
So, is this normal? Does it indicate something's really happening with this person? It feels a bit unreal to be feeling - for want of a better word - a bit "love sick" in middle age. It's like my hormones have gone all over the shop. What's going on?
