(25 m) my gf (24f) has bpd, and I want to know how I can support her as much as possible.

90% of the times when she is angry with me it is completely my fault and justified, however sometimes a small thing will cause her to block me on everything or break up with me for a day etc. When this happens should I keep messaging her trying to sort it out or should I give her space? 

And how seriously should I take the threats? I know that part of bpd is extreme mood swings and it’s not her fault, but in the back of my mind I can’t help thinking maybe she is really breaking up with me for real this time. And it makes me panic.

Any advice is appreciated, thanks
