Hi, I'm new to this thread and the reddit community in general, but I'd like to ask a simple question to those with or potentially with BPD.  
If you know that you have BPD and know full well just how difficult it can be to deal with for your partners as well as yourself, is it okay to start up a relationship?  Of course just knowing you do certain things that arent "okay" is half the battle, but that alone isn't enough to stop you from doing them all together.  Of course I know if you're serious about the relationship you should give some sort of heads up, but a mere warning does not justify the impending storm of pain you bring.  Thank you in advance!
