Well.

If you do care about loving somebody you'd tell them the things that make you love them less.

Then again, I would be extremely self-critical of speaking of things in terms of neizdarības un pāridarījumi. Those are your personal judgements of his actions, not anything half remotely objective.

What does matter is what you *like* and what you *dislike*. Or hate for that matter. You tell him what you dislike and how much (as in,"when you do XXX, that makes me feel like I should leave you [could be also some extrapolation on why it makes you feel so, eg. beacause it makes you feel powerless]"). As precisely as possible. And that's it. Whether it is a neizdarība or pāridarījums doesn't need to concern him. Because it is not what he does, but it is your judgement of him.
