Hi Eva,
Seeing not one but two of your coworkers show up as potential matches on a dating site isn’t surprising. Online dating has become one of the primary ways people meet romantic partners.
Just about everyone, who has a big enough circle of friends, knows someone who is online dating or has done some online dating in the past.
Don’t be surprised if it happens again. Dating sites are prone to resending potential matches that were passed on after some time has passed. Hopefully, you would have met your match and be off dating sites long before then.
