I am sorry for the tzoros you went through in your marriage, and wish you hatzlacha rabbah in finding happiness with someone else.
I know people who have met on Frumster (now JWed, if I am correct), and are very happy. The trick is to get out there and not vegetate. Even if you just go to different events with your age demographic JUST TO ENJOY the event and not put pressure on yourself that it’s to find a shidduch, that’s a good thing. You need to get some space and perspective after a bad situation, so you don’t rebound and get into another bad situation. Network with friends and family and don’t rush into anything, but don’t be overly cautious, either. Keep yourself open-minded to real possibilities. Kol tuv.
