What does this saying mean to you in the context of having experienced a relationship of disorder and visions of future ones thereafter.
Discuss.
I was unfamiliar with the saying so I looked it up; I guess it means, even if you see a swallow or two, you might still have a way to go before summer arrives, and so suffer through more cold weather & snow. But the swallow in the saying is interpreted as a brief, but positive event, and it's hard to consider a relationship with a pwBPD as a positive event

I guess to me, trying to apply it as such, it would mean that just because you suffered through one bad relationship, do not
assume your next one would be good, or perhaps that you are ready to recognize a bad relationship when the warning signs start. You still have more learning to do.
