A simple Question on a minor bump

Hello everybody.
I would like to have your honest opinion , as per your experience.

Have been in contact with a couple (verified) for meeting them and having their first experience.
We had been chating for almost a month mainly throught ...(video calls, chats ,etc). Had direct communication to the Husband also.

Everything was going very smooth. Suddenly one day , both disappeared without a notice. Like ok we found someone else or looking we enjoy the fantasy at least from one of them.

We had great natural chemistry.

Should i pursue them a bit more. Contact them directly on their personal account in insta/messenger.

Or should i let it go.

Looking forward to your feedback
