Accepting what is

I need some help understanding how the Buddhist view on 'accepting what is' and noticing how craving for it to be different to how it is causes suffering, is different to learned helplessness where you become conditioned to give up trying because you believe it's futile. They seem to be very similar to me. In what ways are they different. Is the difference that with Buddhism you don't give up trying? For example if I have a string of failed relationships it can cause learned helplessness and I might give up trying to begin a new one but how would I see it through a Buddhist lense? It's finished because everything is impermanent, now I accept that and I don't give up hope because that's just how it is? But still there is a part of me that feels it's pointless to try again if I know it's going to end in pain again.
