When will I stop being so naive?

Generally I don't think of myself as naive. I've seen a fair number of things in my 32+ years. I certainly don't go around expecting the best of people most of the time. However, this last reality check has been a real doozy. Most of you who know me and my family are aware that we've been through some rough times in the last month. I won't reiterate all of the details here but suffice it to say we are reorienting our life in a big way. Those who have put us in this situation have led me to ask the question with which I titled this post. These were my errors:

• I believed the promises they made to me and my family.
• I assumed their interest in me and my family was genuine.
• I gave them the benefit of the doubt when their actions and choices were questionable.
• I failed to heed the warnings their reputations denoted.
• I believed the feelings and energy we had invested in their lives and well-being would be valued.

So...I was had. Now the question is: was it my fault? Should I have known better or would having been that cynical have ruined other things for me?

I'm left with other questions though: when will I stop feeling so hurt, betrayed, angry and frustrated over how I was treated? When will I no longer wake up in the night having imaginary conversations with them trying to help them see how little integrity they have and what a sad existence they have carved out for themselves? When will I look back on this blog post with a sense of peace? When? Anyone have any answers?
