Hello, I(31M) guess I will begin from the start of this relationship. I became friends with Kay(24F) who is a is an ENM relationship with Jon(24M). Kay and I really hit it off and began being intimate. Fast forward to a couple weeks ago. While Kay and I were chilling Jon came home and was so upset he could barely contain himself. Kay's demeanor changed as well. I just ignored it. The next time I was going to chill with Kay, she couldn't because Jon needed to "apparently process something". A week later I met up with Kay and she said she was overwhelmed and couldn't hang out as often. I just took it at face value. I haven't seen her since. She continues to text me, and insists she wants to see me. I am definitely confused, but should I be worried?
