Don't tell him. Slowly develope a relationship with your friend (i think he is the right one for you). You aren't obligated to tell your ex anything- he is your ex now afterall. If u do feel the need to tell him, make sure your new bf is there with u when u tell him, and if your ex acts like a jerk, let your new bf handle it.
