Butterfly...I would say that knowing you, you don't take sex lightly. So I am going to say it was a mistake, if I am correct. Like everyone else here has said, if you were after casual safe sex for fun, go for it. If you are making emotional ties to someone after a third date, that is a red flag. Too soon. That is just my .02
I am going to be honest here. I think you need to be by yourself for a while and get comfortable with who Butterfly is. Get past all the emotional struggle, and get yourself to a good, stable, happy place. Then...date away.
These are just my thoughts. Whatever you decide to do, we are behind you, always.
