That's a tough one Diaphane. My wife left me for my best friend around eleven years ago. I would have taken a bullet for either one of them. I was really messed up for years.<br />
I guess somewhere down the line I decided that my life is better when I trust people. I'm very open and trusting until someone gives me reason to regret my trust. At that point, I'm done. It feels much better to me to be able, in my mind, to move on when trust has been breached.<br />
As painful and dramatic as the break-up was, as yourself if you were a better and happier person when you took men at their word. If the answer is yes, keep trusting until you find the man who deserves it.
I dont trust you enough to tell you.
You need some alone time and time to heal. Don't date for awhile and just work on you. You will know when you are ready to date again. And men have to prove that they are trustworthy. It's not something that you just do without their proof.
What is the worst thing that could happen if you trust your friend? It sounds like you're not ready to be in a relationship and you may risk losing your friend if you try. On the other hand, what is the potential gain for you if you and your friend do build a romantic relationship? Maybe there is more that he can do to help you recover when you're ready to move on. Good luck.
