Hahahaha!! I don't believe you FuzzyWuzzy!!!
I've been there and done it though. It was an ex of mine from when I was 21. He wasn't the love of my life but was defihnitely the lust of my life. I had long moved on but never got over him. No man ever came close in fact. Eventually we made contact, just as you have, which became e-mails and calls. We then finally arranged to meet up. I had a boyfriend of 5 years at the time and although it started out innocently, I couldn't lie to myself that the idea of meeting my ex was overwhelming, in a sexual way too. When the actual day came, I realised that if I met my ex and I still fancied him, then I wouldn't be able to stop myself. So on the morning of the meeting him I actually ended my relationship with my boyfriend. It was utter chaos for me but I had to follow my feelings.
Anyway, my ex and I met and the chemistry between us was crazy! He was married, and in the next few weeks that passed he was seriously contemplating leaving his wife & child so that we could get back together. He finally opted for his family.
I still received calls from him, periodically, over the next few years. We still felt really strongly for each other. But, it took for me to finally meet a man who shadowed him to be able to move on. I told him straight, and gave him closure and now that episode of my life is over.
In hindsight I don't think it was worth all the emotional drama for either of us. Or for the people around us.
