I do like to talk about things, because I have an overwhelming need to make sense of everything. If someone explains their behavior in a way which makes sense to me, I may partially forgive them. This is what recently happened with my INTJ ex lover. I mostly was upset over the break up because I didn't understand; but now I can mostly see why he did what he did, and it's partially forgivable (assuming he's telling me the truth). I put importance in motivations behind actions (but they don't entirely excuse the actions themselves). If he wants to be friends again he'll have to earn my trust. I don't feel I can trust a person if they don't tell me the truth, and I can't know if they are telling me the truth if I don't understand what they say and it doesn't add up. He's with another woman now and I'm genuinely happy for them, but even if he wasn't I wouldn't want him back because I see now that we really aren't compatible. It would take a lot to convince me otherwise.
Edit: I ended a friendship once because I realized that we literally have nothing in common and I don't enjoy our interaction. Even though she really liked me. I felt bad, but what can you do.
