Although not binary and existing on a spectrum, a more looping or spiral-inclined mind will find a linear mind difficult to deal with, and vice versa. Overt communication will be required to reconcile sufficient understanding if the relationship is to be maintained long-term.
A linear mind focuses on trajectory-based progression, resolution, and closure. While exceptions exist, it will usually see the weight of the past as reduced, cancelled out, or neutralised by present actions. What is carried out in the present can therefore resolve past indiscretions to reach a net-neutral, because through this lens, forgiveness is anchored in evidence of current behaviour, the past is integrated and overwritten. The approach is pragmatically flavoured - "if you are good to me now, it balances what came before".
A spiral mind is layered, operating like a sweeping recurring sonar, and thus holds coexisting past and present internal timelines. Memory is present-tense laced, and vice versa, the dividing lines are not as clean as what their counterpart enjoys. The past remains alive, present, and breathing - superimposed onto their appreciation of present goodwill. Forgiveness is therefore an internal integration process, a deep psychological reprogramming of ongoing re-acceptance, rather than an act of negation in which a net-neutral recalculation enforces functional finality. For spiral minds, both joy and pain can be true simultaneously.
Without clear communication and awareness of this difference, the linear mind will feel as if they are never doing enough, their present efforts written off with little appreciation, while they are continuously punished for the past. Meanwhile, the spiral mind will feel their aches of the past are dismissed and prematurely buried alive, even as they show appreciation for present efforts.
Not sure if the word "prematurely" is required, because it is ongoing, so it feels cut off - "buried alive" is probably sufficient.
