Haha! i just read your post again because i stopped to wonder why "a deux"? And realized what you are asking! Duh I took 4 years of French in school.
What a fascinating fun thing! I have a special best friend from childhood, we sometimes text, rarely get to see each other anymore. He sometimes drops out of contact for a long time, I worry he has bp also. But he is someone I can tell anything to and he will just get it and be so into and tell me I'm magical.
It does take a special friend to stick by when we get grandiose.
