I think your friend did you a great service by suggesting you google this guy. Sure, he may be a great man w/the hots for you...but he's now has a "record" that follows him wherever he goes and he most likely has to check in w/the law enforcement each and every time he moves. There are sites out there for people like us to use to see who are sex offenders in our areas. Go to one of those sites and read up on what "tier" level he is and what he was actually charged with, i.e., strong arm rape, molestation, etc. If it was something to do w/children, then by law in many states, he can't be around children.
If people ask why you aren't interested in this guy, you can always say that you are focusing on yourself and your daughter for now. Info such as what you've uncovered will spread like wildfire if it gets out.
Ginger, I totally agree w/Underdog...you can never be too careful when it comes to your daughter in yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
