Venting is good, it prevents unexpected explosions (Or should anyway). Words like 'should' give me grief. I recently(Few months recently) found out that very little of the time do I 'have to' do something. I want to do something really badly, maybe to advance a goal, but I don't have to do anything. Re: Trust I'm gonna have to re-visit this one sober. I just wrote and promptly deleted a long diatribe about trust, monkeywrenches and similar, but it's neither here nor there. I can say this with confidence. The word 'Trust' sucks because there are a lot of different kinds of relationships/responsibilities that are all amalgamated under that word.
A lot is in that word, conscious, subconscious, even drunk or unconscious. We trust in different ways, and you can specify how you trust people in each relationship. Pick up The Five Dysfunctions of a Team - it's a workplace training book -- but I can see its relevance in any team including romantic teams. Absence of trust is the first dysfunction.
