Hi Nenee, Welcome to the Community!
Before you find “the one,” you’ll date a bunch of other ones. Only the truly lucky find a great relationship built on compatibility, mutual respect, and sexual attraction early on. Most of us have to have all the other types of relationships, to understand what a functional relationship should look like.
Currently I think this is nothing much more than a "Open-Relationship". In this relationship, the two individuals are emotionally committed to one another, but are both free to interact with other people. Commonly known or identified as the "Flirty Type"; This type of relationship mostly only works when both parties aren’t that emotionally invested in one another.
My Advice; Unless there's an emotional attachment or a formal agreement between both of you. RUN!
Otherwise, I would suggest to actually communicate and let time guide you through the stages of your mutual agreement.
Best Wishes To Ya!
