text: about bpd and new relationships? my sister has been dating different guys to try and find someone she can connect with...she has bpd and bipolar2 should she tell these guys up front about her condition, she has on 2 occasions and scared them away, she is on meds and going to therapy and doing well, but her past is horrible,  she wants to be honest but how can she be honest about her life and not mention her illness? so should she or shouldnt she tell? if it's a first date or something then i wouldn't say anything.  if they go out on a few dates and things look like they might be going good then i would tell them.  i also agree with telling the guy that she is on meds and she is doing well with no recent episodes.  there are guys out there that are caring and considerate.  if this scares them off then they weren't worth the time.  good luck to you sister!
