I don't know it seems like you would be able to carry each other through better because you both would have understanding of the other. I have not dated anyone else with a/p but I do have friends that suffer also, but again people suffer a/p in different ways for different reasons. My sister has them but she has them because of a medical condition where as mine is totally thought related (I believe). My therapist says mine is PTSD. I guess just like with most things it depends on the person and who they are? Sorry I couldn't be more helpful.
