Sad that the kind friendship you offered wasn't enough for him, his loss

three this week

I hate when that happens ...I have to do that too in the past

I understand the first part of what you said. (Lots of perverts online!)

But in the second part, are you saying that if you form a friendship with someone, and then realize you are developing a crush, you might drop that person as a friend even if the person did nothing wrong?
