One one of those Christian dating sites I had someone message me and we went back and forth writing a couple times (Only maybe 2 messages each, not about anything too in depth, just a few sentences at a time)... Until he wrote me a long angry message when I didn't reply in what he thought to be a timely matter, lol. I wrote back saying that I wished him the best but didn't feel his future would include the relationship with me that he told me about in the angry message. He then proceeded to send many messages begging me to take him back... All we had talked about was how the weather was and what we did for livings :S I never realized telling someone where I was from was a commitment, lol!
(It was clear in my profile I was looking to be friends before seeing if there was any potential for something further, if at all)
