Thank you for waiting.
I can imagine how sad
and angry you must have been with your ex boyfriend. It sounds like you found he had a live-in girlfriend.
You trusted him. Perhaps, he fell for you and started dating you though he had the girlfriend.
I can understand that you want to meet and talk with him in person.
He may be feeling bad or guilty about his lie or betrayal. He also may be afraid of meeting you as he thinks you are angry at him.
I am not sure if he is the kind of person who you want to care.
But, I know you want him to talk to you face-to-face as you were in a relationship with him until recently.
Perhaps, you may tell him that you are not angry at him (even though you are) and want to talk to him in person, so you can overcome your pain and move on with your life.
I hope he is mature enough to talk to you about what's going on with him in person.
If he does not, he may be just an immature person that you should forget and let go of.
Please let me know if you have more questions or I have overlooked any. Warm regards,
