This is it really, we each have to what we can live with.Out of the things that I know, being able to meet our own eyes in the mirror matters alot.
It would be easy to say I regret all I have done for my son, all the money that was spent but I can't, I don't regret it. I know to the depth of my soul that I did all I could for him. I gave him every possible chance. I don't have to wonder "if only I had done this or that"
We each have a point we get to when we know enough is enough. For some it comes quicker and for others it takes more time.
Copa, I truly hope it goes well with your son.
