Trust

How much your friend needed to know about you to trust you fully?

1) Base on basic instinct where talking to the person frequently?
2) Knowing her/his family background
3) Understand her/his normal character on how the person react to scenarios to see she/he is a honest
4) Check all the information about he/her through internet
5) Scan through his/her pc to look into photos and videos (even though it is private)
6) Read all his/her MSN/skype/yahoo messages to other friends to confirm how much his/her friendship to others?
7) Asking around friends about you to know who you really are to have not double confirm, but hunderd of confirmation just in case 1 person said the different thing about her/him.
8) Read up personal diary
9) Look at personal bank statements
10) Others stuff which inside her/his pc.

If you are face this situation, will be ok for you?
How come it is only 1 side being treat such way, is ok? Is the person being push and bullied when the other think it is alright. Is this healthy relationship? What is I get married and have sex....do I need to video and take photos with bf/gf  to ensure who make I really having sex with only 1 person, or else perceive he/she having sex with everyone. What is the limit of respecting one's private life without stepping too much.
What is the level of personal life is invaded. It is not about keeping secret or hiding any information to a person. But it is based how much you really need to know. If the person did not do any wrong, but doing normal routine life....but friend dont know...is it call as a secret?

Today, I am extremely tired. Yet people insist I'm hiding something.  How many more years I need to face till this scenario stop. When I'm at 60?

I rather let go such people even we were good friends for years as I really want to be free from all these drama and live happily.
