Can you have 100% trust in relationships?
I'm sure it's possible. It seems like a Shangri-La though, and I don't think it's a Shangri-La I'll ever reach. Of course, stranger things have happened.
Should you have 100% trust in relationships?
It's hard, I don't really know what 100% trust is. I mean I can trust people insofar as I accept what they say at face value as a general rule of thumb. Having been cheated on twice, I know that can be dangerous. As a result, I still take things at face value, because paranoia is kind of exhausting. But I just really keep myself aware that all things can end. I think it terribly important to retain some emotional independence and a degree of emotional detachment from all scenarios and people. The level of detachment I exhibit reflects the needs of each given situation. I feel that the emotional detachment is in itself a sign of not displaying 100% trust, because that detachment produces parts of myself that I'm unwilling to share with people, and therefore I am displaying a degree of distrust.
Do both partners in a relationship have to have 100% trust in each other?
No, I can see how it helps, but no. I think it's dangerous when one side is a 100% truster/sharer and the other party is a "keep a small part of myself" person, because it causes heated arguments in my experience. That said, when both parties like to keep a small part of themselves to themselves they can still make a very solid and happy team. I've found (anecdotally) that the 100% truster/sharer folks feel that it's "lonely" being a "keep part of myself" person. I don't really agree with them, but each to their own.
What affects your ability to trust someone?
Previous treatment. If you regularly behave or say things in an inconsistent matter, I'll pick up on it and pull away. Also, I can usually pick up on when someone is trying to hide something because they have an agenda. Effectively, the best way I can describe it is "personal red flag behaviour".
If you are a person who has difficulty trusting in general, how do you learn to trust your partner?
I usually run my issues re. trust past my closest friends. Calling my best friend and telling her that she's meeting me at "our bar" for a drink of Scotch always means "I need your advice". She knows this, and she provides another perspective on any issues I have and helps me understand if I'm just making a big deal out of nothing or if I'm justified in what I'm feeling. If it's a huge problem, I'll call in a couple other friends, which I affectionately call "The Council", and I see what others make of the situations. That way I get a better feel for when the benefit of the doubt is deserved.
How do you keep the lower level of trust from adversely affecting your partner as you learn to trust them?
I don't really decide to take a step like a trust issue confrontation unless I've discussed it above. I hate conflict, so if I can avoid it, I will. I don't think any of my partners have ever known that I've discussed my points of view with 3rd parties in such a manner. I don't breach confidence, they know that much, and I offer them the same level of respect that I would have for myself. This respect tends to take the edge off the fact that I'm edging my way towards trusting them. I also make clear when there are certain issues I simply don't wish to discuss and point out that it's nothing personal, it's just how I am.
If you are someone whose partner doesn't fully trust you, how does it affect you and how does it affect your attitude toward them? (This could be a current relationship or a previous relationship)
It depends on the degree of distrust and the motivations behind it. If it's unbridled jealousy or insecurity on their part, it makes me run a mile. If they just display a certain degree of prudence by keeping a part of themselves to themselves when discussing issues/feelings, well I understand why they'd want to do that. I'm happy to discuss things when people want to discuss them, I'm very easy going like that. So really, it depends how their levels of trust (or lack thereof) affect the relationship itself which governs how I react, if that makes any sense at all...
