"I don't think him showing up to these classes is a positive step forward. I think it is almost more like a guilt thing."
Amen.. That "little voice" is talking up a storm.
"I am guilty of playing the wrongness of the sitch over and over again in my head and there are many times that the emotion of it all hits me like a ton of bricks."
We have all felt wronged. You have to understand dwelling in it won't make it right. 99% of the people here will tell you they are more wronged than you. They would be just as wrong as you are dwelling in it. If I ran up to you on the street and smacked you right across the face and ran away. Are you going to dwell on it for the rest of your life.. or are you going to accept it and move on? Don't think it won't pop into your mind from time to time. Thats what he has done.. a run by smacking. You trying to figure out why he did it.. No hope. You accepting it and moving on.. Hope. Leave the crap behind.. and hope.
"H will take a backseat and I'll be thankful that I don't have to deal with taking care of him, too."
Amen!
