Welcome to our forum.
I think you should try to just take this one day at a time, and try to communicate your feelings to JC and Bee, even if it feels weird or uncomfortable. Relationships tend to change over time, but very often the change is for the good, so try to keep that positive thought in mind. You, Bee, and JC may grow closer because of this, who knows.
Just think how Bee feels when JC can't be with her ... Long-Distance Relationships can be a rough road to travel. Empathizing will probably help you feel less threatened (or left out).
Anyway, I'm glad you joined us on our website.
Love means never having to say, "Put down that meat cleaver!"
