About every two days my FP switches from being a total sweetheart that thinks the world of me to thinking I'm the worse scum on the earth and he lets me know it. I know he has BPD and for a long time I was able to ignore this stuff as just the BPD talking, but now that this has been going on for over a year it's starting to really wear on me and have a negative impact on my well being. These days, it's hard not to internalize all the awful stuff he says after it's been repeated to me so many times.

What can I do to better take care of myself during these splitting episodes? Lately, in an effort to preserve the relationship, I've been taking breaks from him until he calms down and is back in his rational mind but the episodes happen so frequently that's wearing on me emotionally. Should I take longer breaks from him? He generally only splits for about two days and then is nice for about two days. Should I take a week off or something?

I know that some of you have super awesome partners that deal really well with your splitting episodes and have stuck by you despite the BPD. What techniques do they use to get through? Could you share them with me?

Also I'm BPD traits, for reference, but I have much better control over them than my FP does.
