How old are you OP?
I found myself suddenly single at 31, having spent the previous 3.5 years with someone I thought I would marry. It was a massive shock to the system.
I got myself straight onto online dating. I live in a small town, and just thought there was very little chance of me meeting anyone new.
I met one guy who was clearly just out for a bit of fun - I had fun with him, I made the mistake of getting a bit too keen and I didn't take it too well when he disappeared - but it was a lesson well learned, and fun while it lasted.
The second guy I met is now my wonderful boyfriend of 3 years. He was in his late thirties, recently divorced, totally ready for a relationship. We are very, very happy. When I ask my DP what he was looking for in a woman, he said he wouldn't have bothered with anyone much younger, because they wouldn't have been after the same thing as him.
So not all recently divorced men are bitter or just want to play the field. Granted, some do, but that's the same of any age.
Get yourself our there, or online, and keep an open mind. You have to kiss a lot of frogs before you find your prince - god knows I did - but you won't find anyone without trying.
Good luck
