Relationships?

Hi, I am new to this board, but unfortunately not new to RA. I was diagnosed in June 2007 with sero neg RA. I've had several reactions to different meds and I'm still not sure if the meds I'm on now are the right combination for me as I still am hurting daily.  Ok, here's the question. My 7 yr marriage didn't survive the diagnosis and I have now been divorced since December 2008. How do I go about telling any new people (friends or otherwise) about the disease? Do I say anything up front or wait until the relationship is steadier? If I wait, will he/she feel like I wasn't forthcoming? UUUGGGHHH....this sucks lol.  Thanks in advance for any advice!
