Hello, and thanks for your question.
It sounds like you are hurting from this whole thing, and that he means more to you than you thought. Unfortunately, your friend’s new girlfriend has figured out something that’s pretty commonthat it’s extremely hard for men and women to just be friends. She feels threatened by you and the relationship you had with him.
It also sounds like this girlfriend is important to him, or he wouldn’t have cut you off. Seven months is really not very long in a relationship and if it is to survive, he probably should avoid spending time with you. That is very painful, but most relationships never make it past the honeymoon phase and that’s about 2 years.
If his relationship lasts through this period and beyond, he might be able to pick up the friendship where the two of you left off, but in all fairness, he has left it completely up to her to decide. As you said, he chose her to be his girlfriend so he has to remain true to her.
If you continue to try contacting him, you will likely only alienate him further. Respect his boundaries and his wishes if you truly care for him. Let him have some space. He certainly won’t forget you.
Best of luck,
Dr. Diana Walcutt
