How would you feel about your boyfriend/girlfriend meeting up with a friend that they met on Tinder?

They’ve never met before and they didn’t date before bc of being in a relationship. But now she/he wants to meet up to smoke together and she/he is single. They’ve been talking to each other on social media for nearly a year now.
