I am a bit concerned that when you say "As you say I don't need them in my life so I'm giving up. Soon I will close my door and make sure I loose the key. And they will with time forget I ever existed."

What I get from this is that you have situational boundaries. That is a good thing. What concerns me is that you may not be making your boundaries clear to others and giving them a chance to respect them.

If you find your boundaries are invaded, it looks like you simply retreat. This does not help you cope (it feels bad) and it does not give others a fair chance with you. If you just leave, they may not have a clue why and are doomed to repeat their offenses against you unknowingly. It also takes a nice person, you, out of circulation. The world needs a lot more people like you.

Don't mistake being strong and assertive with attack, meanness, and hurting people. You can be assertive and very kind. Can you imagine that Mother Theresa was not strong and assertive?

Also, mean people pick on passive people. A strong person repels unkind people.

Anyway, that is my concern, that you may have problems with certain people and that perhaps you attract their attention by being too accomodating of them. It might be helpful to find ways to strengthen the real you that doesn't let mean people trample on you.
