Bold Move

I had sex with this guy 12 years ago. After that we didn't talk much and eventually we don't talk at all. He then further his studies and me started working and all. Few months back i saw his FaceBook in my friends FaceBook and i check it out. He is living in US now and he is married with two daughter. I had consider very long should i add him or not. Well of course you know many stuff happens in between during those years that's why we started not talking. It's not the sex. Yesterday i requested to add him. Hmmm..... he did approved. So i just text him a "Hello" text. Hmm... hopefully it would be a casual text back. It's a scary moment though...
