People are people. No one is perfect. You will never find someone who is 100% "safe". On a bad day, the person you trust most may yell at you. Somehow (and I wish I knew how) we need to find a balance. To trust, but also to understand that everyone has the capacity to hurt us. Ther are gradations of course... some people will intentionally hurt you time and time again. They deserve to be kicked out of your life. But your T sounds like they want to help. they will be patient. But, yes. They will leave eventually. Everyone does. In the end all we have is ourselves and we need to be comfortable with that.

I talk a good game, I'm not so good at living it out...
