I am not a jealous person, never have been. However, trust is another issue, I am very guarded when I first meet someone, and, even my family and old friends, only know what I want them to know. You can try to pump me all you want and I'll only share what I want to share.
Must have started in my children, living in the home from h@ll, can't shake it, and, really do not want to. My guarded behavior has saved me alot of grief.
