So I just got out of a relationship with my Ex about a month ago. He already has a new girlfriend, so its clear he has already moved on. Now, I hung out with his best friend last night, we kissed, and we agreed to keep this whole thing a secret. Its obvious that we most definitely have sexual tension, and are attracted to each other.. but we must keep it a secret . So my questions are 1. If my ex does find out,will he care even though he has a new girl? 2. Should I stop this secret now or go ahead and keep going to see what happens?
