Here is my formula:
1. Wait until you're truly ready. I can't stress this enough. I fell for someone I shouldn't have because I began dating her before the ink was dry on the divorce papers and was vulnerable. She got to me. Pretty, intelligent, sexy....and a Fatal Attraction-like control freak.
2. Dating websites are just another way to meet people. Don't fall for the BS that some websites have "dimensions of compatibility"....they are just throwing stuff at the walls. I had good luck with Match.
3. Don't expect to hit the ground running. Expect to need a few dates to get back in the game. It's not you.
4. Check back here. We're no experts, or we wouldn't be on this site lol
