I think it depends on the situation, who's to blame for a break of trust. If i expect someone to be like I want him/her to be then i can blame myself for that. There are however social conventions established within society, if we never communicated to not follow these conventions, then the one knowing about the conventions and breaking it can be blamed for that. When we clearly communcated values/behavior and stuff and agreed on it, and someone breaks the "contract" he/she clearly is to blame. And thats why we should never blindly expect but communicate our whishes and values. I do however trust nobody completely, even not my self because i know how a humans mind and eyes can be fooled or fools themselves. I think that is a healthy thing to do in order become more objective on everything. Trust has to be gained first, but will never be on 100%. There is trust in my parents that they love me (it was there from the start of my life) but i don't trust them with everything because i know them. There are situation i had to trust/take the risk, like when i had heart surgery. But generally i only trust in facts and validation and this also just 80%.
